MediumCVSS 4.4 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 17/100)

  • 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: 0.39% (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 (Debian:12) 4.7.8-1; linux (Debian:7) 3.2.84-1; kernel (Red Hat:enterprise_linux:6::client) 0:2.6.32-696.el6.

Low priority for now. Upgrade to linux (Debian:12) 4.7.8-1; linux (Debian:7) 3.2.84-1; kernel (Red Hat:enterprise_linux:6::client) 0:2.6.32-696.el6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr call, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions.
