"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: gfs2: corrige use-after-free en gfs2_glock_shrink_scan. El indicador GLF_LRU se marca en lru_lock en gfs2_glock_remove_from_lru() para eliminar el glock de la lista lru en __gfs2_glock_put(). En la ruta de escaneo de reducci\u00f3n, la misma bandera se borra en lru_lock pero debido a cond_resched_lock(&lru_lock) en gfs2_dispose_glock_lru(), se puede avanzar en el lado de venta sin eliminar la glock de la lista de lru. Mantenga GLF_LRU en la ventana de ejecuci\u00f3n abierta por cond_resched_lock(&lru_lock) para garantizar un comportamiento correcto en ambos lados; borre GLF_LRU despu\u00e9s de list_del en lru_lock."
