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

mailbox: mailbox-test: free channels on probe error

On probe error, free the previously obtained channels. This not only
prevents a leak, but also UAF scenarios because the client structure
will be removed nonetheless because it was allocated with devm.
