Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.17.4

Description A race condition in the Linux kernel allows guest OS users to cause a denial of service, resulting in a guest OS crash. This can be achieved through a crafted application that performs an MMIO transaction or a PIO transaction, triggering a guest userspace emulation error report.

Recommendations For Linux kernel versions prior to 3.17.4, update to version 3.17.4 or later to resolve the issue. As a temporary workaround, consider restricting access to MMIO and PIO transactions to minimize the risk of exploitation.
