In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix call removal to use RCU safe deletion
Fix rxrpc call removal from the rxnet->calls list to use list_del_rcu()
rather than list_del_init() to prevent stuffing up reading
/proc/net/rxrpc/calls from potentially getting into an infinite loop.
This, however, means that list_empty() no longer works on an entry that's
been deleted from the list, making it harder to detect prior deletion. Fix
this by:
Firstly, make rxrpc_destroy_all_calls() only dump the first ten calls that
are unexpectedly still on the list. Limiting the number of steps means
there's no need to call cond_resched() or to remove calls from the list
here, thereby eliminating the need for rxrpc_put_call() to check for that.
rxrpc_put_call() can then be fixed to unconditionally delete the call from
the list as it is the only place that the deletion occurs.
