Local privilege escalation via receive-handler race
Published Sep 15, 2026 · Updated Sep 15, 2026
Out-of-bounds write in Google Android's google_mba_recv_msg kernel handler allows local users to escalate privileges. A race condition in google_mba_poll.c lets concurrent message handling write beyond the intended buffer boundary. Exploitation requires local access to an affected Pixel-family-specific kernel, needs no user interaction, and can elevate an existing user's privileges.
