Vulnerability Details : CVE-2021-47270
In the Linux kernel, the following vulnerability has been resolved:
usb: fix various gadgets null ptr deref on 10gbps cabling.
This avoids a null pointer dereference in
f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm}
by simply reusing the 5gbps config for 10gbps.
