CVE-2024-57933

Local system crash via unguarded XSK queues

Published Jan 21, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux kernel gve driver allows local users to crash the system through XSK pool operations. The enable and disable paths dereference a receive-queue pointer without first confirming that queues exist, while xsk_wakeup can race with queue removal. Reachability requires the gve driver and an XSK operation while the interface is down or its queues disappear; the documented consequence is loss of availability.
