CVE-2026-57043 · Severity: info · Published 2026-11-10

Google Pixel devices contain a vulnerability in the TIPC (Transport and Inter-Process Communication) virtio device driver that can corrupt memory when probe initialization fails. An attacker with local system access could exploit this to escalate privileges and gain system-level execution. No user interaction is required for exploitation.

Technologies: [Google Pixel Firmware](https://junglewise.ai/threats/technologies/pixel-firmware). Vendors: [Google](https://junglewise.ai/threats/vendors/google).

## Technical details

The vulnerability is an off-by-one error in the cleanup loop within tipc_dev_probe() of tipc_virtio_dev.c, triggered when device probe fails. This logic error allows out-of-bounds memory access during cleanup. The vulnerability requires local execution privileges and is exploitable without user interaction, enabling local privilege escalation to system level.
