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: 0.25% (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 03db61c43c8e2729896fda6b9a95c7fb5c875c20, 67c2c6d0564ca05348ba4f8f6eaf7a0713f56c15, 911fcc95b530615b484e8920741fc5e4bc4e684a.

Low priority for now. Upgrade to Linux Linux 03db61c43c8e2729896fda6b9a95c7fb5c875c20, 67c2c6d0564ca05348ba4f8f6eaf7a0713f56c15, 911fcc95b530615b484e8920741fc5e4bc4e684a or later.
