Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
usb: gadget: f_rndis: Refactor bind path to use __free()<br />
<br />
After an bind/unbind cycle, the rndis->notify_req is left stale. If a<br />
subsequent bind fails, the unified error label attempts to free this<br />
stale request, leading to a NULL pointer dereference when accessing<br />
ep->ops->free_request.<br />
<br />
Refactor the error handling in the bind path to use the __free()<br />
automatic cleanup mechanism.
