| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel's USB gadget driver contains a memory leak in the raw gadget driver. Specifically, the
raw dev->count is incremented before the raw queue event() function is invoked. If raw queue event() returns an error, the raw release() function is not triggered, preventing dev free() from being called, which results in a memory leak. The issue occurs during the handling of USB Raw Gadget events and can lead to system instability. The fix involves invoking kref get() only when raw queue event() returns successfully. The function raw open() is involved in the process, and the raw ioctl() function is also mentioned in the context of the issue.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
