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

Description The issue is related to a null pointer dereference in the Linux kernel's USB gadget functionality when using 10gbps cabling. This is avoided by reusing the 5gbps config for 10gbps, which prevents the null pointer dereference in functions such as f ecm, f eem, f hid, f loopback, f printer, f rndis, f serial, f sourcesink, f subset, and f tcm.

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