CVE-2026-55318Network attack vector

Remote code execution via race-driven use-after-free

Published Sep 15, 2026 · Updated Sep 15, 2026

Use-after-free flaws in the Google Android kernel allow remote attackers to execute code without user interaction via race conditions. Multiple undisclosed kernel locations can race object-lifetime changes and then access objects after their storage has been freed. No additional execution privileges are required, and successful exploitation grants code execution; Google has not published the affected functions or reachable input path.
