Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A issue in the Linux kernel has been resolved, related to the gadget workqueue not being properly cleaned up after device removal. This can lead to new work being scheduled in the gadget->work workqueue, as observed with the dwc3 driver. The problem occurs when device del() is called, which can result in the scheduling of new work. This issue is addressed by moving the flush work() call after device del() to ensure the workqueue is properly cleaned up.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
