Description

usb: gadget: f_rndis: Refactor bind path to use __free()

In the Linux kernel, the following vulnerability has been resolved:

usb: gadget: f_rndis: Refactor bind path to use __free()

After an bind/unbind cycle, the rndis->notify_req is left stale. If a

subsequent bind fails, the unified error label attempts to free this

stale request, leading to a NULL pointer dereference when accessing

ep->ops->free_request.

Refactor the error handling in the bind path to use the __free()

automatic cleanup mechanism.

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required.
