Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak issue has been identified in the Linux kernel, specifically in the mousevsc probe() function. The problem occurs when hid add device() returns an error, and hid destroy device() is not called to free the allocated hid dev in hid allocate device().

Recommendations For the Linux kernel, ensure that hid destroy device() is called when hid add device() returns an error to prevent the memory leak. As a temporary workaround, consider implementing error handling to free allocated resources in hid allocate device() when hid add device() fails.
