CVE-2024-56725: octeontx2-pf: handle otx2_mbox_get_rsp errors in otx2_dcbnl.c

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 54e8b501b3ea9371e4a9aa639c75b681fa5680f0, 69297b0d3369488af259e3a7cf53d69157938ea1, 6ee6cf42dc5230425cfce1ffefa5a8d8a99e6fce; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1.

Low priority for now. Upgrade to Linux Linux 54e8b501b3ea9371e4a9aa639c75b681fa5680f0, 69297b0d3369488af259e3a7cf53d69157938ea1, 6ee6cf42dc5230425cfce1ffefa5a8d8a99e6fce; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1 or later.
