Descriptions
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. [1] https://lore.kernel.org/all/00000000000073b14905ef2e7401@google.com/
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: bpf, sockmap: no permita que sock_map_{close,destroy,unhash} se llame a sí mismo. Las devoluciones de llamada del proto sock_map nunca deberían llamarse a sí mismas por diseño. Protéjase contra bugs como [1] y salga del bucle recursivo para evitar un desbordamiento de la pila que favorezca una fuga de recursos.
