CVE-2025-38226: media: vivid: Change the siize of the composing

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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 00da1c767a6567e56f23dda586847586868ac064, 4.10, 4.15; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1.

Low priority for now. Upgrade to Linux Linux 00da1c767a6567e56f23dda586847586868ac064, 4.10, 4.15; azl3 kernel 6.6.92.2-2 on Azure Linux 3.0 6.6.96.1-1 or later.
