CriticalCVSS 9.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 46/100)

  • 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: 23.5% (FIRST EPSS); higher than 97.8% 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) 4.5.2-1; kernel (Red Hat:enterprise_linux:5::client) 0:2.6.18-417.el5; kernel-debug (Red Hat:enterprise_linux:5::client) 0:2.6.18-417.el5.

Add it to your regular patch cycle. Upgrade to linux (Debian:12) 4.5.2-1; kernel (Red Hat:enterprise_linux:5::client) 0:2.6.18-417.el5; kernel-debug (Red Hat:enterprise_linux:5::client) 0:2.6.18-417.el5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Use-after-free vulnerability in the __sys_recvmmsg function in net/socket.c in the Linux kernel before 4.5.2 allows remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing.
