  2. Vulnerabilities (CVE)
  3. CVE-2021-47167
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.

Summary
  • (es) 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.
