CriticalCVSS 9.3 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 38/100)

  • 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: 2.9% (FIRST EPSS); higher than 87.5% of all records.
  • Fixed version: linux (Debian:12) 3.13.6-1; kernel-rt (Red Hat:enterprise_mrg:2:server:el6) 0:3.10.33-rt32.34.el6rt; kernel-rt-debug (Red Hat:enterprise_mrg:2:server:el6) 0:3.10.33-rt32.34.el6rt.

Low priority for now. Upgrade to linux (Debian:12) 3.13.6-1; kernel-rt (Red Hat:enterprise_mrg:2:server:el6) 0:3.10.33-rt32.34.el6rt; kernel-rt-debug (Red Hat:enterprise_mrg:2:server:el6) 0:3.10.33-rt32.34.el6rt or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Race condition in the inet_frag_intern function in net/ipv4/inet_fragment.c in the Linux kernel through 3.13.6 allows remote attackers to cause a denial of service (use-after-free error) or possibly have unspecified other impact via a large series of fragmented ICMP Echo Request packets to a system with a heavy CPU load.
