CVE-2024-42252: closures: Change BUG_ON() to WARN_ON()

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: 0.21% (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 339b84ab6b1d66900c27bd999271cb2ae40ce812, 5d85f2ab79d5918a66539ebf046c099f7448db8d, c894a74756478bb7aec894bcc513add3d554c0cf; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.64.2-9; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.64.2-9.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 339b84ab6b1d66900c27bd999271cb2ae40ce812, 5d85f2ab79d5918a66539ebf046c099f7448db8d, c894a74756478bb7aec894bcc513add3d554c0cf; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.64.2-9; azl3 kernel 6.6.92.2-1 on Azure Linux 3.0 6.6.64.2-9 or later.
