Google Android: Insecure default value allows coprocessor memory modification
Summary
An insecure default value in multiple locations of the Android platform allows non-secure software to modify the instruction and data memory of a coprocessor. An attacker with local access and System-level privileges can use this to escalate privileges. No user interaction is required. The affected coprocessor is not named in the sources, and the Google bulletin row for this CVE could not be confirmed.
Affected
- Google Android devices; the sources name the Android kernel as the affected component, but this is unconfirmed.
- Specific affected builds and version ranges: Unknown.
- Pixel devices are in scope of the Pixel Update Bulletin, November 2026.
Fixed in
- Security patch level 2026-11-05 or later, according to OSV. This could not be verified against the Google bulletin row for this CVE.
- Pixel 6 and Pixel 6 Pro no longer receive updates; their last patch level was October 2026, so no fix is available for them.
Workaround
Unknown. No non-patch mitigation is documented.
Exploitation
- No known exploitation in the wild; not listed in CISA KEV in the sources reviewed.
- No public proof of concept found. VulDB reports the technical details as unknown.
- CISA SSVC assessment: exploitation none, automatable no, technical impact total.
Our recommendation
- Update managed Pixel devices to security patch level 2026-11-05 or later and verify the patch level on each device.
- Retire unsupported models such as Pixel 6 and Pixel 6 Pro.
- Restrict local access to managed mobile devices and monitor for updates to the NVD entry and CISA KEV.
- Severity: NVD gives CVSS 6.7 (Medium); VulDB gives 8.8 as a third-party estimate.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
In multiple locations, there is a possible way to modify coprocessor instruction and data memory from non-secure software due to an insecure default value. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
