Descriptions

In the Linux kernel, the following vulnerability has been resolved:

tipc: fix a possible memleak in tipc_buf_append

__skb_linearize() doesn't free the skb when it fails, so move
'*buf = NULL' after __skb_linearize(), so that the skb can be
freed on the err path.

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tipc: soluciona un posible memleak en tipc_buf_append __skb_linearize() no libera el skb cuando falla, así que mueve '*buf = NULL' después de __skb_linearize(), para que el skb se puede liberar en la ruta de error.
