CVE-2026-20471
In DA, there is a possible out of bounds write due to a missing bounds check. This could lead to local denial of service, if an attacker has physical access to the device, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS10991588 (Note: For MT6880, MT6890, MT6990, MT6988, MT6986, MT6813) / AUTO00851171 (Note: For MT2735, MT2737); Issue ID: MSV-7790.
No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.
Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.
Affected & fixed versions by distribution
Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.
No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
