CVE-2024-36915: nfc: llcp: fix nfc_llcp_setsockopt() unsafe copies

HighCVSS 7.1 · v3.1—No exploit Fix available

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: 0.25% (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 0f106133203021533cb753e80d75896f4ad222f8, 298609e7069ce74542a2253a39ccc9717f1d877a, 29dc0ea979d433dd3c26abc8fa971550bdc05107.

Low priority for now. Upgrade to Linux Linux 0f106133203021533cb753e80d75896f4ad222f8, 298609e7069ce74542a2253a39ccc9717f1d877a, 29dc0ea979d433dd3c26abc8fa971550bdc05107 or later.
