In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Don't let sock_map_{close,destroy,unhash} call itself
sock_map proto callbacks should never call themselves by design. Protect
against bugs like [1] and break out of the recursive loop to avoid a stack
overflow in favor of a resource leak.
