MediumCVSS 6.2 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 24/100)

  • 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).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: linux (Debian:12) 4.3.5-1; linux (Debian:7) 3.2.73-2+deb7u3; linux (Debian:8) 3.16.7-ckt20-1+deb8u4.

Low priority for now. Upgrade to linux (Debian:12) 4.3.5-1; linux (Debian:7) 3.2.73-2+deb7u3; linux (Debian:8) 3.16.7-ckt20-1+deb8u4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes.
