CVE-2024-35835: net/mlx5e: fix a double-free in arfs_create_groups

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.62% (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 2501afe6c4c9829d03abe9a368b83d9ea1b611b7, 3c6d5189246f590e4e1f167991558bdb72a4738b, 42876db001bbea7558e8676d1019f08f9390addb.

Low priority for now. Upgrade to Linux Linux 2501afe6c4c9829d03abe9a368b83d9ea1b611b7, 3c6d5189246f590e4e1f167991558bdb72a4738b, 42876db001bbea7558e8676d1019f08f9390addb or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix a double-free in arfs_create_groups When `in` allocated by kvzalloc fails, arfs_create_groups will free ft->g and return an error. However, arfs_create_table, the only caller of arfs_create_groups, will hold this error and call to mlx5e_destroy_flow_table, in which the ft->g will be freed again.
