drm/amd/display: Check if modulo is 0 before dividing.

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: 0.26% (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 07efce8269a038c37814eb656b4de14aa3015fc6, 10ef82d6e0af5536ec64770c07f6bbabfdd6977c, 49947b906a6bd9668eaf4f9cf691973c25c26955.

Low priority for now. Upgrade to Linux Linux 07efce8269a038c37814eb656b4de14aa3015fc6, 10ef82d6e0af5536ec64770c07f6bbabfdd6977c, 49947b906a6bd9668eaf4f9cf691973c25c26955 or later.
