"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: do not BUG_ON() when freeing tree block after error\n\nWhen freeing a tree block, at btrfs_free_tree_block(), if we fail to\ncreate a delayed reference we don't deal with the error and just do a\nBUG_ON(). The error most likely to happen is -ENOMEM, and we have a\ncomment mentioning that only -ENOMEM can happen, but that is not true,\nbecause in case qgroups are enabled any error returned from\nbtrfs_qgroup_trace_extent_post() (can be -EUCLEAN or anything returned\nfrom btrfs_search_slot() for example) can be propagated back to\nbtrfs_free_tree_block().\n\nSo stop doing a BUG_ON() and return the error to the callers and make\nthem abort the transaction to prevent leaking space. Syzbot was\ntriggering this, likely due to memory allocation failure injection."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: btrfs: no hacer BUG_ON() al liberar un bloque de \u00e1rbol despu\u00e9s de un error Al liberar un bloque de \u00e1rbol, en btrfs_free_tree_block(), si no podemos crear una referencia retrasada, no nos ocupamos del error y simplemente hacemos un BUG_ON(). El error m\u00e1s probable que ocurra es -ENOMEM, y tenemos un comentario que menciona que solo puede ocurrir -ENOMEM, pero eso no es cierto, porque en caso de que los qgroups est\u00e9n habilitados, cualquier error devuelto por btrfs_qgroup_trace_extent_post() (puede ser -EUCLEAN o cualquier cosa devuelta por btrfs_search_slot(), por ejemplo) se puede propagar de vuelta a btrfs_free_tree_block(). As\u00ed que deja de hacer un BUG_ON() y devuelve el error a los llamadores y haz que aborten la transacci\u00f3n para evitar fugas de espacio. Syzbot estaba activando esto, probablemente debido a la inyecci\u00f3n de fallo de asignaci\u00f3n de memoria."
