CVE-2013-1796: Linux Kernel

Medium severity, CVSS 6.8. EPSS: 0.9% chance of exploitation in the next 30 days.

The kvm_set_msr_common function in arch/x86/kvm/x86.c in the Linux kernel through 3.8.4 does not ensure a required time_page alignment during an MSR_KVM_SYSTEM_TIME operation, which allows guest OS users to cause a denial of service (buffer overflow and host OS memory corruption) or possibly have unspecified other impact via a crafted application.

Affected products

• Linux Linux Kernel: up to and including 3.8.4; version 3.8.0 only; version 3.8.1 only; version 3.8.2 only; version 3.8.3 only
