CVE-2023-53651: Input: exc3000 - properly stop timer on shutdown

MediumCVSS 5.5 · v3.1—No exploit Fix available

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: 0.21% (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 0914496ec5ca04dfafe1a5d562477029b1f92b96, 526a177ac6353d65057eadb5d6edafc168f64484, 79c81d137d36f9635bbcbc3916c0cccb418a61dd.
  • Severity is disputed: the assigning authority (CNA) scores it 7.8, NVD 5.5.

Low priority for now. Upgrade to Linux Linux 0914496ec5ca04dfafe1a5d562477029b1f92b96, 526a177ac6353d65057eadb5d6edafc168f64484, 79c81d137d36f9635bbcbc3916c0cccb418a61dd or later.
