MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.12% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0b7f56084cc3d7766bf274b71cd14cc9674b76bf, 141c81849fab2ad4d6e3fdaff7cbaa873e8b5eb2, 505630dd1ebf4b53d3f2866c057ddd93157a24d8.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0b7f56084cc3d7766bf274b71cd14cc9674b76bf, 141c81849fab2ad4d6e3fdaff7cbaa873e8b5eb2, 505630dd1ebf4b53d3f2866c057ddd93157a24d8 or later.
