Noroxi assessment
Priority: Monitor (action score 18/100)
- 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: 0.37% (FIRST EPSS).
- Fixed version: fai-kernels (Debian:3.1) 1.9.1sarge8; kernel-image-2.6.8-alpha (Debian:3.1) 2.6.8-17sarge1; kernel-image-2.6.8-amd64 (Debian:3.1) 2.6.8-17sarge1.
Low priority for now. Upgrade to fai-kernels (Debian:3.1) 1.9.1sarge8; kernel-image-2.6.8-alpha (Debian:3.1) 2.6.8-17sarge1; kernel-image-2.6.8-amd64 (Debian:3.1) 2.6.8-17sarge1 or later.
