Local privilege escalation via side-channel permission bypass
Published Sep 15, 2026 · Updated Sep 15, 2026
Permission bypass in Google Android's Pixel-family kernel allows local users to gain elevated privileges through side-channel disclosure. Google identifies multiple affected locations but has not published the specific kernel routines or operations that expose permission-related side-channel information. Exploitation requires local access, needs no user interaction or prior execution privileges, and is limited to affected Pixel-family builds.
