MediumCVSS 6.8 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 1.7% (FIRST EPSS); higher than 78.4% of all records.
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: linux (Debian:12) 4.8.7-1; linux (Debian:7) 3.2.84-1; kernel (Red Hat:enterprise_linux:7::client) 0:3.10.0-862.el7.

Low priority for now. Upgrade to linux (Debian:12) 4.8.7-1; linux (Debian:7) 3.2.84-1; kernel (Red Hat:enterprise_linux:7::client) 0:3.10.0-862.el7 or later.
