CVE-2024-46818: drm/amd/display: Check gpio_id before used as array index

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: 0.26% (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 0184cca30cad74d88f5c875d4e26999e26325700, 08e7755f754e3d2cef7d3a7da538d33526bd6f7c, 276e3fd93e3beb5894eb1cc8480f9f417d51524d; 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 0184cca30cad74d88f5c875d4e26999e26325700, 08e7755f754e3d2cef7d3a7da538d33526bd6f7c, 276e3fd93e3beb5894eb1cc8480f9f417d51524d; Azure Linux 3.0 ARM 6.6.51.1-5; Azure Linux 3.0 x64 6.6.51.1-5 or later.
