Linux Kernel '/include/xen/blkif.h' 32-on-64 Support Denial Of Service Vulnerability

The Linux kernel is prone to a denial-of-service vulnerability because the software fails to perform sanity checks when handling values when running 32-bit paravirtualized guests on a 64-bit host.

Local, privileged attackers can leverage the issue to crash the kernel and deny service to legitimate users.
