CVE-2024-35959

Local service interruption via unlocked mlx5e cleanup

Published May 20, 2024 · Updated May 11, 2026

Improper cleanup in the Linux mlx5e driver allows local users to interrupt service during failed network-device initialization. mlx5e_priv_init() invokes mlx5e_selq_cleanup() on failure, which calls mlx5e_selq_apply() without holding priv->state_lock while replacing an RCU-protected pointer. Reachability requires low-privileged local access and an mlx5 network device whose initialization enters the failure path; no data disclosure or modification is reported.
