"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix inode list leak during backref walking at resolve_indirect_refs()\n\nDuring backref walking, at resolve_indirect_refs(), if we get an error\nwe jump to the 'out' label and call ulist_free() on the 'parents' ulist,\nwhich frees all the elements in the ulist - however that does not free\nany inode lists that may be attached to elements, through the 'aux' field\nof a ulist node, so we end up leaking lists if we have any attached to\nthe unodes.\n\nFix this by calling free_leaf_list() instead of ulist_free() when we exit\nfrom resolve_indirect_refs(). The static function free_leaf_list() is\nmoved up for this to be possible and it's slightly simplified by removing\nunnecessary code."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: btrfs: correcci\u00f3n de fuga de lista de inodos durante el recorrido de backref en resolve_indirect_refs() Durante el recorrido de backref, en resolve_indirect_refs(), si obtenemos un error saltamos a la etiqueta 'out' y llamamos a ulist_free() en la ulist 'parents', que libera todos los elementos en la ulist - sin embargo, eso no libera ninguna lista de inodos que pueda estar adjunta a elementos, a trav\u00e9s del campo 'aux' de un nodo ulist, por lo que terminamos filtrando listas si tenemos alguna adjunta a los unodes. Arregle esto llamando a free_leaf_list() en lugar de ulist_free() cuando salimos de resolve_indirect_refs(). La funci\u00f3n est\u00e1tica free_leaf_list() se mueve hacia arriba para que esto sea posible y se simplifica ligeramente eliminando c\u00f3digo innecesario."
