CVE-2022-27818

Hotkey disclosure and service interruption via fixed socket

Published Apr 7, 2022 · Updated Aug 3, 2024

Local resource hijacking in SWHKD before 1.2.0 allows local users to intercept hotkey commands or prevent hotkey processing. The privileged swhkd daemon connects to the fixed /tmp/swhkd.sock path, allowing a pre-created attacker socket to receive commands intended for swhks. Exploitation requires local filesystem and UNIX-socket access; the result is command disclosure or failure of the hotkey service to start and deliver events.
