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

Description A flaw exists in the USB function device call musb gadget queue() within the musb gadget.c file. When a request's length exceeds the endpoint packet size and is buffer mapped(req) returns false, the rxstate() function may copy all data in the FIFO to the request buffer, potentially causing an out-of-bounds write. The issue occurs when adding a request to musb ep::req list. A length check has been added to mitigate this.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
