CVE-2024-46804: drm/amd/display: Add array index check for hdcp ddc access

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 0ee4387c5a4b57ec733c3fb4365188d5979cd9c7, 2a63c90c7a90ab2bd23deebc2814fc5b52abf6d2, 4e70c0f5251c25885c31ee84a31f99a01f7cf50e.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0ee4387c5a4b57ec733c3fb4365188d5979cd9c7, 2a63c90c7a90ab2bd23deebc2814fc5b52abf6d2, 4e70c0f5251c25885c31ee84a31f99a01f7cf50e or later.
