Descriptions
In the Linux kernel, the following vulnerability has been resolved:
NFS: Fix an Oopsable condition in __nfs_pageio_add_request()
Ensure that nfs_pageio_error_cleanup() resets the mirror array contents,
so that the structure reflects the fact that it is now empty.
Also change the test in nfs_pageio_do_add_request() to be more robust by
checking whether or not the list is empty rather than relying on the
value of pg_count.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: NFS: corrija una condición de Oopsable en __nfs_pageio_add_request() Asegúrese de que nfs_pageio_error_cleanup() restablezca el contenido de la matriz reflejada, de modo que la estructura refleje el hecho de que ahora está vacía. También cambie la prueba en nfs_pageio_do_add_request() para que sea más sólida verificando si la lista está vacía o no en lugar de confiar en el valor de pg_count.
