MediumCVSS 4.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 16/100)

  • 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. Administrator privileges are required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Linux Linux 1d8c270de5eb74245d72325d285894a577a945d9, 4889f117755b2f18c23045a0f57977f3ec130581, 6e2e374403bf73140d0efc9541cb1b3bea55ac02; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.43.1-7; azl3 kernel 6.6.43.1-7 on Azure Linux 3.0 6.6.43.1-7.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1d8c270de5eb74245d72325d285894a577a945d9, 4889f117755b2f18c23045a0f57977f3ec130581, 6e2e374403bf73140d0efc9541cb1b3bea55ac02; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.43.1-7; azl3 kernel 6.6.43.1-7 on Azure Linux 3.0 6.6.43.1-7 or later.
