Executive brief
A race condition vulnerability exists in the TIPC (Transparent Inter-Process Communication) virtualization driver component of Google Pixel devices' Linux kernel. An attacker with local access can exploit this memory corruption flaw to escalate privileges without requiring special permissions, potentially gaining full control over the device.
Technical details
A race condition exists in the handle_unmap_req function of tipc_virtio_dev.c in the Linux kernel component used by Google Pixel devices. The vulnerability allows concurrent access to shared memory structures without proper synchronization, leading to memory corruption. An attacker with local code execution capability can trigger the race condition to cause corruption that results in privilege escalation to kernel-level access. The issue affects Pixel devices and is addressed in Android security patch level 2026-09-05 or later; the specific vulnerable code path requires no additional execution privileges beyond local code execution and does not require user interaction.
