"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: NFSv4: corrige una desreferencia de puntero NULL en pnfs_mark_matching_lsegs_return(). Confirme los cambios de144ff4234f _pnfs_return_layout() para llamar a pnfs_mark_matching_lsegs_return() pasando NULL como argumento de estructura pnfs_layout_range. Desafortunadamente, pnfs_mark_matching_lsegs_return() no verifica si tenemos un valor aqu\u00ed antes de eliminar la referencia a \u00e9l, lo que provoca un error. Puedo alcanzar este bloqueo de manera consistente cuando ejecuto pruebas b\u00e1sicas de Connectathon en NFS v4.1/v4.2 contra Ontap."
