CVE-2024-26788: dmaengine: fsl-qdma: init irq after reg initialization

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: 0.22% (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 3cc5fb824c2125aa3740d905b3e5b378c8a09478, 4529c084a320be78ff2c5e64297ae998c6fdf66b, 474d521da890b3e3585335fb80a6044cb2553d99.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 3cc5fb824c2125aa3740d905b3e5b378c8a09478, 4529c084a320be78ff2c5e64297ae998c6fdf66b, 474d521da890b3e3585335fb80a6044cb2553d99 or later.
