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

media: rc: sunxi-cir: Unregister rc device on probe failure

After rc_register_device() succeeds, later probe failures must undo the

registration with rc_unregister_device(). The current error path jumps to

the allocation cleanup label and only calls rc_free_device(), leaving the

rc device registration and resources created by rc_register_device()

behind.

Add a registered-device unwind label for the IRQ lookup, IRQ request, and

hardware initialization failure paths. Keep rc_free_device() for failures

before rc_register_device() succeeds. (NVD)
