Descriptions

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.

En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: usb: repara varios gadgets null ptr deref en cableado de 10gbps. Esto evita una desreferencia de puntero null en f_{ecm,eem,hid,loopback,printer,rndis,serial,sourcesink,subset,tcm} simplemente reutilizando la configuración de 5 gbps para 10 gbps.
