CVE-2024-53833

Local privilege escalation via LWIS out-of-bounds write

Published Jan 3, 2025 · Updated Jan 6, 2025

Out-of-bounds write in the LWIS kernel driver on supported Google Pixel devices allows local users to escalate privileges. The prepare_response_locked function in lwis_transaction.c insufficiently validates transaction response data before writing it beyond an intended buffer boundary. Exploitation requires local low-privileged access but no user interaction or additional execution privileges, and successful corruption grants elevated execution on the device.
