Published Aug 24, 2026 · Updated Aug 24, 2026

Use-after-free in the Zircon kernel pager proxy in Google Android F30.1.1 allows remote authenticated users to gain kernel privileges. The pager proxy retains or dereferences an object after its lifetime ends, leaving freed memory reachable during pager handling. Exploitation requires low-privileged access and crosses the userspace boundary to kernel authority without user interaction.
