CVE-2024-53090

Estado: ModificadaMedia (5.5)—

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

afs: Fix lock recursion

afs_wake_up_async_call() can incur lock recursion. The problem is that it is called from AF_RXRPC whilst holding the ->notify_lock, but it tries to take a ref on the afs_call struct in order to pass it to a work queue - but if the afs_call is already queued, we then have an extraneous ref that must be put... calling afs_put_call() may call back down into AF_RXRPC through rxrpc_kernel_shutdown_call(), however, which might try taking the ->notify_lock again.

This case isn't very common, however, so defer it to a workqueue. The oops looks something like:
