Noroxi assessment

Priority: Plan (action score 55/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 67.7% (FIRST EPSS); higher than 99.3% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.20.1.el8_5; linux (Debian:11) 5.10.92-2; linux (Debian:12) 5.16.10-1.
  • Mentioned 5 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to kernel-tools-libs-devel (AlmaLinux:8) 4.18.0-348.20.1.el8_5; linux (Debian:11) 5.10.92-2; linux (Debian:12) 5.16.10-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed. This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network.
