CVE-2024-36030: octeontx2-af: fix the double free in rvu_npc_freemem()

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.22% (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 6e965eba43e9724f3e603d7b7cc83e53b23d155e, f5aa87a2c0a72132ffc793fb0a5375b2a65d520a.

Low priority for now. Upgrade to Linux Linux 6e965eba43e9724f3e603d7b7cc83e53b23d155e, f5aa87a2c0a72132ffc793fb0a5375b2a65d520a or later.
