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: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 114204d25e1dffdd3a0c1cfbba219afd344f4b4f, 4a034ece7e2877673d9085d6e7ed45e6ee40b761, 9163a5b4ed290da4a7d23fa92533e0e81fd0166e.

Low priority for now. Upgrade to Linux Linux 114204d25e1dffdd3a0c1cfbba219afd344f4b4f, 4a034ece7e2877673d9085d6e7ed45e6ee40b761, 9163a5b4ed290da4a7d23fa92533e0e81fd0166e or later.
