CVE-2024-56783: netfilter: nft_socket: remove WARN_ON_ONCE on maximum cgroup level

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: 0.20% (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 2f9bec0a749eb646b384fde0c7b7c24687b2ffae, 6.1.120, 6.11; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.76.1-1; azl3 kernel 6.6.76.1-1 on Azure Linux 3.0 6.6.76.1-1.

Low priority for now. Upgrade to Linux Linux 2f9bec0a749eb646b384fde0c7b7c24687b2ffae, 6.1.120, 6.11; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.76.1-1; azl3 kernel 6.6.76.1-1 on Azure Linux 3.0 6.6.76.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_socket: remove WARN_ON_ONCE on maximum cgroup level cgroup maximum depth is INT_MAX by default, there is a cgroup toggle to restrict this maximum depth to a more reasonable value not to harm performance. Remove unnecessary WARN_ON_ONCE which is reachable from userspace.
