**Name of the Vulnerable Software and Affected Versions** Linux kernel (affected versions not specified) **Description** The issue is related to a debugfs directory leak in the Linux kernel's ULPI (UTMI+ Low Pin Interface) driver. The ULPI per-device debugfs root is named after the ulpi device's parent, but the `ulpi unregister interface` function tries to remove a debugfs directory named after the ulpi device itself. This results in the directory sticking around and preventing subsequent (deferred) probes from succeeding. The fix involves changing the directory name to match the ulpi device. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
