—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 6.1.187, c36289e3c5e83286974ef68c20c821fd5b63801c, ce282d8de71f07f0056ea319541141152c65f552.

Low priority for now. Upgrade to Linux Linux 6.1.187, c36289e3c5e83286974ef68c20c821fd5b63801c, ce282d8de71f07f0056ea319541141152c65f552 or later.
