drm/amd/display: Initialize get_bytes_per_element's default to 1

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: 0.25% (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 1f9f8186e239222f1c8d3dd73bf3bc6ae86c5e76, 3334ab72cbba55a632f24579cd47c4a4e5e69cda, 4067f4fa0423a89fb19a30b57231b384d77d2610; Azure Linux 3.0 ARM 6.6.57.1-2; Azure Linux 3.0 x64 6.6.57.1-2.

Low priority for now. Upgrade to Linux Linux 1f9f8186e239222f1c8d3dd73bf3bc6ae86c5e76, 3334ab72cbba55a632f24579cd47c4a4e5e69cda, 4067f4fa0423a89fb19a30b57231b384d77d2610; Azure Linux 3.0 ARM 6.6.57.1-2; Azure Linux 3.0 x64 6.6.57.1-2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Initialize get_bytes_per_element's default to 1 Variables, used as denominators and maybe not assigned to other values, should not be 0. bytes_per_element_y & bytes_per_element_c are initialized by get_bytes_per_element() which should never return 0. This fixes 10 DIVIDE_BY_ZERO issues reported by Coverity.
