CVE-2014-3610: Canonical Ubuntu Linux

Medium severity, CVSS 5.5. EPSS: 0.6% chance of exploitation in the next 30 days.

The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c.

• Canonical Ubuntu Linux: version 10.04 only; version 12.04 only
• Debian Debian Linux: version 7.0 only
• Linux Linux Kernel: before 3.17.2 (fixed in 3.17.2)
