CVE-2024-29741

Local privilege escalation via S2MPU mitigation bypass

Published Apr 5, 2024 · Updated Feb 28, 2026

Privilege escalation in the S2MPU component of Google Android kernel builds allows local users to gain elevated privileges without interaction. The pblS2mpuResume function in s2mpu.c processes resume-time mitigation state with a logic error that leaves the intended S2MPU protection bypassable. Exploitation requires local low-privilege code execution on affected Pixel hardware and grants privileges beyond those already held.
