CVE-2024-46726: drm/amd/display: Ensure index calculation will not overflow

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 3dc6bb57dab36b38b7374af0ac916174c146b6ed, 733ae185502d30bbe79575167b6178cfb6c5d6bd, 8e2734bf444767fed787305ccdcb36a2be5301a2; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 3dc6bb57dab36b38b7374af0ac916174c146b6ed, 733ae185502d30bbe79575167b6178cfb6c5d6bd, 8e2734bf444767fed787305ccdcb36a2be5301a2; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5 or later.
