Name of the Vulnerable Software and Affected Versions Linux kernel versions through 3.17.2

Description The issue is related to the KVM subsystem in the Linux kernel, where a flaw in the arch/x86/kvm/emulate.c file allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. A guest user with access to I/O or MMIO region can exploit this flaw to crash the guest.

Recommendations For Linux kernel versions through 3.17.2, update to a version later than 3.17.2 to resolve the issue. As a temporary workaround, consider restricting access to I/O or MMIO regions to minimize the risk of exploitation.
