In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix missing locking causing hanging calls
If a call gets aborted (e.g. because kafs saw a signal) between it being
queued for connection and the I/O thread picking up the call, the abort
will be prioritised over the connection and it will be removed from
local->new_client_calls by rxrpc_disconnect_client_call() without a lock
being held. This may cause other calls on the list to disappear if a race
occurs.
Fix this by taking the client_call_lock when removing a call from whatever
list its ->wait_link happens to be on.
