GrapheneOS [Unofficial]

Notable changes in version 2:

• handle top bar title text overflow with ellipsis instead of wrapping
• handle rename of Twitter to X and replace twitter.com with x.com
• update AndroidX Compose UI library to 1.7.0-beta04
• fixes for state restoration when resuming or changing configuration

A full list of changes from the previous release (version 1) is available through the Git commit log between the releases.

Releases of the app are published in the GrapheneOS app repository. You can use the GrapheneOS app repository client on Android 12 or later for automatic updates. Each release is initially pushed out through the Alpha channel, followed by the Beta channel and then finally the Stable channel.

Wise has quietly started allowing people to add our EUR account and send us money again.

Issue appears to be fully resolved. Similarly to how they quietly started blocking that without any notice, it has stopped without a reply to our support request.

"counterterrorism operation being conducted by a U.S.-allied Western government"

Selectively leaking info to sway public opinion is a classic move. Over 3 years after https://technologyreview.com/2021/03/26/1021318/google-security-shut-down-counter-terrorist-us-ally/, no info about which US ally or supposed terrorist group.

Here's an example of a "counterterrorism operation" by a U.S.-allied Western government targeting political opponents with NSO exploits:

https://citizenlab.ca/2022/04/catalangate-extensive-mercenary-spyware-operation-against-catalans-using-pegasus-candiru/

Is this what's being referenced? Perhaps they mean the Polish government targeting the political opposition this way.

https://theguardian.com/world/2022/feb/17/more-polish-opposition-figures-found-to-have-been-targeted-by-pegasus-spyware

Is this the "counterterrorism operation" by a U.S.-allied Western government that's being referenced? If saying the country and "terrorist" group involved paints a flattering picture of these exploit tools, why aren't they saying which ones are involved?

A more extreme example of a US ally doing a "counterterrorism operation" using NSO exploits:

https://en.wikipedia.org/wiki/Assassination_of_Jamal_Khashoggi

Sure, not a "Western government". Does "U.S.-allied Western government" include Hungary, Turkey, Israel, Japan and South Korea? "Western" meaning what exactly?

Forensic data extraction tools are similar. They use exploits to extract data from devices. Many people claim that since they're primarily used by law enforcement it means they're primarily used for good. They're widely used to target arbitrary people at protests, borders, etc.

GrapheneOS is heavily focused on defending against both remote exploitation and local data extraction. As part of that work, we recently reported 2 vulnerabilities being actively exploited by forensic companies. These are now fixed for Pixels, but not yet other Android devices.

We certainly support fixing these bugs...

Changes in version 126.0.6478.122.0:

• update to Chromium 126.0.6478.122

A full list of changes from the previous release (version 126.0.6478.110.0) is available through the Git commit log between the releases.

This update is available to GrapheneOS users via our app repository and will also be bundled into the next OS release. Vanadium isn't yet officially available for users outside GrapheneOS, although we plan to do that eventually. It won't be able to provide the WebView outside GrapheneOS and will have missing hardening and other features.

We questioned why this was only listed in the Pixel Update Bulletin and they agree:

After review we agree with your assessment that this is an Android issue and as such we are working on backports to include this in a future Android Security Bulletin.

April 2024 monthly update for Pixels included a partial mitigation for this vulnerability in firmware (CVE-2024-29748).

Android 14 QPR3 released in June 2024 includes a full solution for all Android devices by implementing the wipe-without-reboot proposal we made in our report.

The issue is that in practice, only Pixels ship the monthly and quarterly updates. Other devices only ship monthly security backports, not the monthly/quarterly releases of AOSP. They were only going to get the patch when they updated to Android 15. They're now going to backport.

The other vulnerability we reported at the same time for reset attacks was assigned CVE-2024-29745 but that's a firmware/hardware issue without a software solution available so we can't get them to include it in the Android Security Bulletin unless we convince Qualcomm to fix it.

Every vulnerability in the Android Open Source Project that's deemed to be High/Critical severity is meant to be backported to yearly releases from the past 3 years (currently Android 12, 13 and 14). Low/Moderate severity vulnerabilities are NOT generally backported though.

The issue is that they're really listing patches rather than vulnerabilities. Both of the vulnerabilities we originally reported impact all Android devices, but both got Pixel specific patches in April 2024 and therefore got treated as Pixel specific vulnerabilities instead.

Since the complete solution for the device admin API is an Android Open Source Project (AOSP) patch, they're going to backport it. Since there's no way to frame the reset attack issue as an AOSP issue, there isn't a good way to get it fixed for other devices through this system.

These patched vulnerabilities and other currently unpatched vulnerabilities are being exploited by forensic tools used by states to target journalists, political opponents, activists, arbitrary people crossing borders, etc. Sure, they target lots of drug users / dealers too...

Wise silently disabled adding our EUR account as a contact on Wise, blocking people from transferring us money on the platform. They're stonewalling us about it. We've received 3 donations via EUR today, so transfers from other banks to our Wise account are still working fine...

Wise's initial response was they're unable to talk to us about it for security/regulatory reasons and needed to talk to the people trying to send us money instead. Fine, but they stonewalled each of those people and said they couldn't say anything for security/regulatory reasons.

Wise won't tell us which of our accounts has disabled functionality or which functionality has been disabled. It only appears to impact receiving EUR via Wise, not sending it and not other currencies. We likely triggered a false positive and they simply default to stonewalling.

Our experience with financial services is that the only way to solve the problems is to post on social media about it, get significant traction and eventually someone who works with the company prods them internally to get it sorted out, which ends up being a quick/simple fix.

Appears to be a Wise software bug causing our EUR account to show up as deleted to other Wise users, but it otherwise works for receiving from external banks and sending money. Wise's support staff simply appear to badly trained and stonewall referring to irrelevant AML policy.

GrapheneOS Info app is now available through our app repository and will be included in the next release of the OS. It supports viewing recent OS release notes, provides info on our chat rooms, forum and active social media accounts along with offering all the donations methods.

This will be included in the next release of GrapheneOS. We also plan to make significant improvements to the other GrapheneOS apps in the near future. We'll also be working towards replacing or overhauling each of the user-facing AOSP apps as we already did with the Camera app.

We recently completely replaced the Setup Wizard shown during the initial installation with a modern replacement following the standard setup design style. We'll be adding more functionality there and our app repository to help people get started including obtaining their apps.

Changes in version 120:

• update max supported version of Play Store to 41.5

A full list of changes from the previous release (version 119) is available through the Git commit log between the releases (only changes to the gmscompat_config text file and config-holder/ directory are part of GmsCompatConfig).

This update is available to GrapheneOS users via our app repository and will also be bundled into the next OS release.

Our latest release improves our hardware-based USB-C port attack surface reduction. Our previous software-based feature has been extended and merged into it as a 2nd layer of enforcement. We've also extended it to disable pogo pins data at a hardware level on the Pixel Tablet.

Our previous feature is now fully obsolete and has been removed on devices with the newer approach, which is a nice simplification. We've rewritten the documentation here:

https://grapheneos.org/features#usb-c-port-and-pogo-pins-control

Older approach is now only used on the Pixel 5a and earlier end-of-life devices.

Our documentation explains why our approach is much better than the standard Android USB HAL toggle available to device admin apps since Android 12. Standard approach only disables USB connections in the OS. It leaves USB-C and pogo pins enabled at both the OS and hardware level.

The standard approach also can't block new USB connections without ending existing USB connections. It has no distinction between those things. It forces a choice between ending existing USB connections when locking or delaying using it at all until the last USB connection ends.

Several operating systems previously included a port of our legacy software-based approach and mistakenly moved to the less secure approach of disabling USB via the standard USB HAL after the last USB connection ends. It's less secure than simply extending our legacy feature...

Since Android 14 QPR3 is a major release, the end-of-life Pixel 4a (5G) and Pixel 5 receiving extended support releases from GrapheneOS will need to be ported to it with additional work in a future release, which is done as a low priority. Pixel 4a (5G) and Pixel 5 are end-of-life and shouldn't be used anymore due to lack of security patches for firmware and drivers. We provide extended support for harm reduction.

Pixel 6 and later use the open source Trusty OS for the Trusted Execution Environment (TrustZone) and secure core firmware.

Starting with this month's quarterly release (Android 14 QPR3), Trusty sources and baseline applets are part of the Android Open Source Project in trusty/.

Not everything is published, particularly Tensor specific portions. It'd be helpful to publish the rest to make it easier to audit and propose improvements.

They still need to publish the Titan M2 fork of OpenTitan too, which they committed to eventually doing several years ago.

OpenTitan was created to replace their secure elements based on ARM secure cores with a custom RISC-V design across their servers, Chromebooks and Pixel phones/tablets. Pixel 6 and later have a RISC-V secure element (Titan M2), but they still need to publish Pixel specific code.

Upstream OpenTitan project is currently focused on implementing the TPM specification for desktop/server use. TPM is a horrible secure element API. It isn't what's used on Pixels where they got to design APIs for usage by the Android Open Source Project based on what it needs.

This is closely related to publishing the rest of the Trusty code used for Pixels, since they implement communication using authenticated encryption between the SoC secure core and the standalone secure element. Non-Pixel Android ecosystem could benefit a lot from all this code.

Changes since the 2024061300 release:

• revert upstream refactoring of the device association code in Android 14 QPR3 due to it introducing a chain crash bug at boot in edge cases with associated devices such as paired Android Wear devices
• kernel (5.10): update to latest GKI LTS branch revision Vanadium: update to version 126.0.6478.71.0

We've found a serious bug in Android 14 QPR3 which can lead to devices getting stuck in a crash loop on boot after adding a device association such as a WearOS pairing. This impacts both stock Pixel OS and AOSP. Google is aware and reverted the broken change in Android 15 Beta 2.

Today, we plan to do a release fixing this serious issue and the AOSP Bluetooth module regression breaking pairing with the Galaxy Watch6 device we purchased for testing due to previous Bluetooth regressions in Android 14 QPR2 breaking it. Today's release should reach Stable.

If you don't depend on Bluetooth, you might as well update to the current OS release in the Beta channel and then switch back to Stable. Only reason it's not in the Stable channel yet is these 2 issues. There's another minor upstream Settings UI style issue which doesn't matter.

Changes in version 126.0.6478.71.0:

• update to Chromium 126.0.6478.71
• set default toolbar shortcut to new tab

• fix boot-time optimizing apps progress UI with Android 14 QPR3 and enable it again
• fix regression in our Android 14 QPR3 port resulting in PIN scrambling in secondary users being determined by the Owner user setting
• revert major upstream Android 14 QPR3 Internet quick tile overhaul since it broke the functionality in secondary users
• temporarily add back disabling memory tagging and hardened_malloc for surfaceflinger since Android 14 QPR3 didn't fix it as expected
• disable temporary unconditional system crash notifications since we've gotten the initial feedback we needed via the previous release
• add additional null check for eSIM wiping done as part of the duress PIN/password wipe implementation to avoid harmless exception
• Settings: remove blank illustration from "Screen resolution" screen
• Vanadium: update to version 126.0.6478.50.1

Chromium v126 broke support for the built-in password manager on Android. We've fixed it in Vanadium 126.0.6478.50.1:

https://grapheneos.social/@GrapheneOS/112609618525601248

We'll be filing a Chromium issue. We've had success reporting similar regressions for Android operating systems without Google Play.

We'd greatly appreciate if more GrapheneOS users helped with the Alpha/Beta testing of Vanadium releases. Can enable the Alpha/Beta channel by selecting Vanadium in the app repository client (Apps) and changing release channel with the menu. We might need to make it more visible.

If you decide to help with testing for our apps or the OS, please join our Alpha/Beta testing chat room and report regressions there right away. See https://grapheneos.org/contact#community-chat for details. Can use Matrix, Discord, Telegram or even IRC (libera.chat) since it's bridged.

There are a lot of people helping with testing the OS releases in the Alpha and Beta channels, but very few people helping with the apps. We expect most people aren't aware there are Alpha and Beta channels for the app repository too, since it's tucked away in the Apps menu.

Changes in version 126.0.6478.50.1:

• restore past Password Manager settings behavior from before v126, although Chromium has deprecated it with the intention to remove it in 6 months so we'll need to talk to them about it
• enable feature flag for passkey support (already handled via Vanadium Config update)
• enable skipping autofill compatibility checks (already handled via Vanadium Config update)
• explicitly disable include_both_v8_snapshots for the upcoming v127 release since it will increase build time and APK size for a feature that's only available as an opt-in experiment

CVE-2024-32896 which is marked as being actively exploited in the wild in the June 2024 Pixel Update Bulletin is the 2nd part of the fix for CVE-2024-29748 vulnerability we described here:

https://grapheneos.social/@GrapheneOS/112204428984003954

As we explained there, none of this is actually Pixel specific.

Bulletin:

https://source.android.com/docs/security/bulletin/pixel/2024-06-01

Attribution to us:

https://source.android.com/docs/security/overview/acknowledgements

CVE-2024-32896 and CVE-2024-29748 refer to the same vulnerability of interrupting reboot for wipes via the device admin API, which applies to all devices.

CVE-2024-32896 is a full fix in AOSP as part of Android 14 QPR3. It's not at all Pixel specific.

This is being widely incorrectly reported in tech news coverage. Pixel Update Bulletins are almost entirely patches for vulnerabilities which apply to other devices too. Android Security Bulletins are the list of what other OEMs are required to fix, not the full list of patches.

We explained this in our previous thread:

https://grapheneos.social/@GrapheneOS/112204437363495338

CVE-2024-29748 was a mitigation for the issue implemented in the Pixel bootloader. Full solution is implementing wipe-without-reboot, which is now a standard feature in Android 14 QPR3 released as part of AOSP.

Our 2024052100 release backported the upstream wipe-without-reboot feature being shipped in the June 2024 release of Android (Android 14 QPR3): https://grapheneos.org/releases#2024052100.

We extended it to make it more robust via extra redundancy in our 2024060400 release: https://grapheneos.org/releases#2024060400.

There were 2 main issues:

1. memory not wiped when booting firmware-based fastboot mode, allowing exploiting it to get previous OS memory
2. AOSP device admin API depends on reboot-to-recovery to wipe before Android 14 QPR3

Neither is issue is being fixed outside Pixels yet.

Each month, Android has a new version released. These are the monthly, quarterly (QPR) and yearly releases. The baseline monthly security patches are NOT the monthly releases of Android. They're backports of a SUBSET of the patches with High/Critical severity, not all patches.

Most devices only ship the backported patches to older Android releases (12, 13 and 14). Pixels ship the monthly, quarterly and yearly releases. Other devices will mostly get the 2nd vulnerability fix when they update to Android 15. They'll have to fix the 1st issue on their own.

We have a thread about forensic company capabilities at https://grapheneos.social/@GrapheneOS/112462756293586146 based on leaked Cellebrite documentation. Shows GrapheneOS does a much better job than iOS/Android blocking exploits and only Pixel 6 and later or iPhone 12 and later successfully stop brute forcing.

This is the first release of GrapheneOS based on Android 14 QPR3, the 3rd quarterly maintenance/feature release for Android 14.

We've found at least one new issue with the Android Open Source Project 14 QPR3 Bluetooth module and are already working on resolving it. We'll have a quick follow-up release fixing the Bluetooth regression and other issues discovered during public Alpha testing.

Pixel 8a is now supported as part of the standard Android releases instead of having a device branch based on Android 14 QPR1. We've had stable releases for it available since May 15th (1 day after launch) based on our last QPR1-based release (2024030300). Pixel 8a users will be getting the GrapheneOS improvements from March, April, May and June along with the Android 14 QPR2 and QPR3 improvements so it's a much larger release for the Pixel 8a.
