CVE-2024-42146: drm/xe: Add outer runtime_pm protection to xe_live_ktest@xe_dma_buf

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: 0.19% (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 0888d15ea45ba8ef4508edd1123ea5ad95b58994, f9116f658a6217b101e3b4e89f845775b6fb05d9.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0888d15ea45ba8ef4508edd1123ea5ad95b58994, f9116f658a6217b101e3b4e89f845775b6fb05d9 or later.
