**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** An issue exists in the `pci slot trylock()` function where error handling is incorrectly implemented. Following a change that delegated the bridge device's `pci dev trylock()` to `pci bus trylock()`, the corresponding `pci dev unlock()` call was not removed from the failure path. This results in the system attempting to unlock a device that was not locked, leading to either a warning that a lock is being released without being held or the incorrect unlocking of a lock belonging to another thread. **Recommendations** Remove the redundant `pci dev unlock()` call on the failure path within the `pci slot trylock()` function.
