"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnfs: Fix oops in nfs_netfs_init_request() when copying to cache\n\nWhen netfslib wants to copy some data that has just been read on behalf of\nnfs, it creates a new write request and calls nfs_netfs_init_request() to\ninitialise it, but with a NULL file pointer. This causes\nnfs_file_open_context() to oops - however, we don't actually need the nfs\ncontext as we're only going to write to the cache.\n\nFix this by just returning if we aren't given a file pointer and emit a\nwarning if the request was for something other than copy-to-cache.\n\nFurther, fix nfs_netfs_free_request() so that it doesn't try to free the\ncontext if the pointer is NULL."

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nfs: Arreglar oops en nfs_netfs_init_request() al copiar a cach\u00e9 Cuando netfslib quiere copiar algunos datos que acaban de leerse en nombre de nfs, crea una nueva solicitud de escritura y llama a nfs_netfs_init_request() para inicializarla, pero con un puntero de archivo NULL. Esto hace que nfs_file_open_context() d\u00e9 un error; sin embargo, en realidad no necesitamos el contexto nfs ya que solo vamos a escribir en la cach\u00e9. Arregla esto simplemente devolviendo si no se nos da un puntero de archivo y emitiendo una advertencia si la solicitud fue para algo distinto a copiar a cach\u00e9. Adem\u00e1s, arregla nfs_netfs_free_request() para que no intente liberar el contexto si el puntero es NULL."
