This leads to a Use-after-Free if\nthe skb is taken concurrently from the session queue due to a CTS."

Este parche corrige un Use-after-Free encontrado por syzbot. El problema es que se toma un skb de la cola de skb por sesi\u00f3n, sin incrementar el recuento de referencias. Esto conduce a un use after free si el skb se toma simult\u00e1neamente de la cola de sesi\u00f3n debido a un CTS."
