CVE-2024-35785: tee: optee: Fix kernel panic caused by incorrect error handling

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: 0.23% (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 4b12ff5edd141926d49c9ace4791adf3a4902fe7, 5.10.215, 5.15.154.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 4b12ff5edd141926d49c9ace4791adf3a4902fe7, 5.10.215, 5.15.154 or later.
