Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.7

Description The issue arises from the translate desc function in drivers/vhost/vhost.c, which does not properly handle cross-region descriptors. This allows guest OS users to obtain host OS privileges by leveraging KVM guest OS privileges.

Recommendations For Linux kernel versions prior to 3.7, update to version 3.7 or later to resolve the issue. As a temporary workaround, consider restricting access to KVM guest OS privileges to minimize the risk of exploitation.
