| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to the Linux kernel's USB gadget functionality, specifically the dwc3 driver. It involves a null pointer dereference that can occur when handling partially completed requests. The
dwc3 request->num queued sgs variable is decremented upon completion, but if a request is only partially completed, this variable no longer accurately reflects the total number of queued SG entries. This can lead to a null pointer dereference when attempting to access a non-existent SG entry.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
