CVE-2024-57931: selinux: ignore unknown extended permissions

MediumCVSS 5.5 · v3.1—No exploit Fix available

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: 0.22% (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 712137b177b45f255ce5687e679d950fcb218256, 900f83cf376bdaf798b6f5dcb2eae0c822e908b6, c1dbd28a079553de0023e1c938c713efeeee400f.

Low priority for now. Upgrade to Linux Linux 712137b177b45f255ce5687e679d950fcb218256, 900f83cf376bdaf798b6f5dcb2eae0c822e908b6, c1dbd28a079553de0023e1c938c713efeeee400f or later.
