CVE-2024-36288: SUNRPC: Fix loop termination condition in gss_free_in_token_pages()

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: 0.74% (FIRST EPSS); higher than 54.7% of all records.
  • 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 0a1cb0c6102bb4fd310243588d39461da49497ad, 4a77c3dead97339478c7422eb07bf4bf63577008, 4cefcd0af7458bdeff56a9d8dfc6868ce23d128a.
  • Severity is disputed: the assigning authority (CNA) scores it 9.8, NVD 5.5.

Low priority for now. Upgrade to Linux Linux 0a1cb0c6102bb4fd310243588d39461da49497ad, 4a77c3dead97339478c7422eb07bf4bf63577008, 4cefcd0af7458bdeff56a9d8dfc6868ce23d128a or later.
