CVE-2024-46772: drm/amd/display: Check denominator crb_pipes before used

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: 0.23% (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 04805efe8623f8721f3c01182ea73d68e88c62d8, b9264aa24f628eba5779d1c916441e0cedde9b3d, ea79068d4073bf303f8203f2625af7d9185a1bc6.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 04805efe8623f8721f3c01182ea73d68e88c62d8, b9264aa24f628eba5779d1c916441e0cedde9b3d, ea79068d4073bf303f8203f2625af7d9185a1bc6 or later.
