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: 0.55% (FIRST EPSS).
- No special conditions are required; it is repeatable.
- Fixed version: fai-kernels (Debian:3.1) 1.9.1sarge8; hostap-modules-i386 (Debian:3.1) 1:0.3.7-1sarge3; i2c (Debian:3.1) 1:2.9.1-1sarge2.
Low priority for now. Upgrade to fai-kernels (Debian:3.1) 1.9.1sarge8; hostap-modules-i386 (Debian:3.1) 1:0.3.7-1sarge3; i2c (Debian:3.1) 1:2.9.1-1sarge2 or later.
