CVE-2026-0121

Local information disclosure via VPU race

Published Mar 10, 2026 · Updated Mar 10, 2026

Information disclosure in the VPU component of Google Android kernel allows local users to read freed memory through a race condition. A VPU race leaves memory reachable after it is freed, and a subsequent read returns stale contents from the freed allocation. Exploitation requires local access, needs no additional execution privileges or user interaction, and is limited to information disclosure.
