CVE-2024-53149: usb: typec: ucsi: glink: fix off-by-one in connector_status

Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 0.31% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 4a22918810980897393fa1776ea3877e4baf8cca, 6ba6f7f29e0dff47a2799e60dcd1b5c29cd811a5, 8a2273e5c1beb285729aa001422967b4711c53fe.

Low priority for now. Upgrade to Linux Linux 4a22918810980897393fa1776ea3877e4baf8cca, 6ba6f7f29e0dff47a2799e60dcd1b5c29cd811a5, 8a2273e5c1beb285729aa001422967b4711c53fe or later.
