Google Android Pixel: Use-after-free in Bluetooth stack
Summary
A use-after-free vulnerability in the Android Bluetooth component (bluetooth_ccc.cc, BluetoothCccHandlerCallbackImpl) affects Pixel devices. The CVE record describes possible remote code execution without user interaction or extra privileges, but Google's October 2026 Pixel bulletin classifies the issue as elevation of privilege (EoP), so the RCE claim is unconfirmed. The CVSS vector lists network access, which is questionable for Bluetooth, and an attacker would likely need to be in radio range. No exploitation is documented.
Affected
- Google Pixel devices without security patch level 2026-10-05 or later
- Affected Android versions and builds: Unknown.
- Other Android OEMs: Unknown.
Fixed in
- Security patch level 2026-10-05 or later (Pixel Update Bulletin, October 2026)
Workaround
- No vendor workaround known. Installing the patch is the fix.
- Until patched, disable Bluetooth where it is not needed, e.g. via MDM policy.
Exploitation
- Not known exploited. CISA SSVC: Exploitation none, Automatable yes, Technical Impact total.
- No public proof of concept found.
Our recommendation
- Update managed Pixel devices and BYOD phones with access to company data to security patch level 2026-10-05 or later, preferably via MDM.
- Restrict Bluetooth on devices where it is not required.
- Monitor Google and CISA KEV for updated details on the impact type and exploitation.
