In the Linux kernel, the following vulnerability has been resolved:
Input: ims-pcu - fix use-after-free and double-free in disconnect
ims_pcu_disconnect() only intended to perform cleanup when the primary
(control) interface is unbound. However, it currently relies on the
interface class to distinguish between control and data interfaces.
A malicious device could present a data interface with the same class
as the control interface, leading to premature cleanup and potential
use-after-free or double-free.
Switch to verifying that the interface being disconnected is indeed
the control interface.
