CVE-2024-39505: drm/komeda: check for error-valued pointer

MediumCVSS 5.5 · v3.1—No exploit Fix available

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: 0.28% (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 0674ed1e58e2fdcc155e7d944f8aad007a94ac69, 3b1cf943b029c147bfacfd53dc28ffa632c0a622, 86042e3d16b7e0686db835c9e7af0f9044dd3a56.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0674ed1e58e2fdcc155e7d944f8aad007a94ac69, 3b1cf943b029c147bfacfd53dc28ffa632c0a622, 86042e3d16b7e0686db835c9e7af0f9044dd3a56 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: drm/komeda: check for error-valued pointer komeda_pipeline_get_state() may return an error-valued pointer, thus check the pointer for negative or null value before dereferencing.
