New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The translate_desc function in drivers/vhost/vhost.c in the Linux kernel before 3.7 does not properly handle cross-region descriptors, which allows guest OS users to obtain host OS privileges by leveraging Kernel-base Virtual Machine (KVM) guest OS privileges.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL15732.
