CVE-2023-52524: net: nfc: llcp: Add lock when modifying device list

HighCVSS 7.8 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.18% (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 191d87a19cf1005ecf41e1ae08d74e17379e8391, 29c16c2bf5866326d5fbc4a537b3997fcac23391, 4837a192f6d06d5bb2f3f47d6ce5353ab69bf86b.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 191d87a19cf1005ecf41e1ae08d74e17379e8391, 29c16c2bf5866326d5fbc4a537b3997fcac23391, 4837a192f6d06d5bb2f3f47d6ce5353ab69bf86b or later.
