HighCVSS 7.8 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 33/100)

  • 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: 5% (FIRST EPSS); higher than 92.4% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: linux-2.6 (Debian:4.0) 2.6.18.dfsg.1-13etch1; kernel (Red Hat:enterprise_linux:5::client) 0:2.6.18-8.1.4.el5; kernel-debuginfo (Red Hat:enterprise_linux:5::client) 0:2.6.18-8.1.4.el5.

Low priority for now. Upgrade to linux-2.6 (Debian:4.0) 2.6.18.dfsg.1-13etch1; kernel (Red Hat:enterprise_linux:5::client) 0:2.6.18-8.1.4.el5; kernel-debuginfo (Red Hat:enterprise_linux:5::client) 0:2.6.18-8.1.4.el5 or later.
