CVE-2024-35959: net/mlx5e: Fix mlx5e_priv_init() cleanup flow

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 6bd77865fda662913dcb5722a66a773840370aa7, ad26f26abd353113dea4e8d5ebadccdab9b61e76, ecb829459a841198e142f72fadab56424ae96519.

Low priority for now. Upgrade to Linux Linux 6bd77865fda662913dcb5722a66a773840370aa7, ad26f26abd353113dea4e8d5ebadccdab9b61e76, ecb829459a841198e142f72fadab56424ae96519 or later.

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fix mlx5e_priv_init() cleanup flow When mlx5e_priv_init() fails, the cleanup flow calls mlx5e_selq_cleanup which calls mlx5e_selq_apply() that assures that the `priv->state_lock` is held using lockdep_is_held(). Acquire the state_lock in mlx5e_selq_cleanup().
