CVE-2024-43904: drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencing

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: 0.23% (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 10c20d79d59cadfe572480d98cec271a89ffb024, 15c2990e0f0108b9c3752d7072a97d45d4283aea, 16a8a2a839d19c4cf7253642b493ffb8eee1d857.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 10c20d79d59cadfe572480d98cec271a89ffb024, 15c2990e0f0108b9c3752d7072a97d45d4283aea, 16a8a2a839d19c4cf7253642b493ffb8eee1d857 or later.

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Add null checks for 'stream' and 'plane' before dereferencing This commit adds null checks for the 'stream' and 'plane' variables in the dcn30_apply_idle_power_optimizations function. These variables were previously assumed to be null at line 922, but they were used later in the code without checking if they were null. This could potentially lead to a null pointer dereference, which would cause a crash. The null checks ensure that 'stream' and 'plane' are not null before they are used, preventing potential crashes. Fixes the below static smatch checker: drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:938 dcn30_apply_idle_power_optimizations() error: we previously assumed 'stream' could be null (see line 922) drivers/gpu/drm/amd/amdgpu/../display/dc/hwss/dcn30/dcn30_hwseq.c:940 dcn30_apply_idle_power_optimizations() error: we previously assumed 'plane' could be null (see line 922)
