CVE-2025-36916

Local privilege escalation via double-fetch race

Published Dec 11, 2025 · Updated Dec 11, 2025

Race condition in the Android kernel on supported Pixel devices allows local users to escalate privileges through the TPU driver. PrepareWorkloadBuffers in gxp_main_actor.cc fetches shared workload-buffer data twice without sufficient synchronization, allowing it to change between reads. Low-privileged local execution and a successful race are required; no user interaction is needed, and the resulting privileges can affect data and service availability.
