Last modified

CVE-2013-1796 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.95% chance of exploitation in the next 30 days.
