HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 4.6% (FIRST EPSS); higher than 91.9% of all records.
  • Anyone who can reach it over the internet 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) 4.5.4-1; linux (Debian:7) 3.2.81-1; kernel-pae (SUSE:Linux Enterprise Point of Sale 11 SP3) 3.0.101-0.47.86.1.

Low priority for now. Upgrade to linux (Debian:12) 4.5.4-1; linux (Debian:7) 3.2.81-1; kernel-pae (SUSE:Linux Enterprise Point of Sale 11 SP3) 3.0.101-0.47.86.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The llc_cmsg_rcv function in net/llc/af_llc.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory by reading a message.
