CVE-2024-46811: drm/amd/display: Fix index may exceed array range within fpu_update_bw_bounding_box

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.24% (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 188fd1616ec43033cedbe343b6579e9921e2d898, 4003bac784380fed1f94f197350567eaa73a409d, 6d8685dd9718e0613f7c64253500874021b9efc9; 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 188fd1616ec43033cedbe343b6579e9921e2d898, 4003bac784380fed1f94f197350567eaa73a409d, 6d8685dd9718e0613f7c64253500874021b9efc9; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5 or later.
