CVE-2013-4587: Input Validation
Published Nov 15, 2013
·Updated
Array index error in the kvmvmioctlcreatevcpu function in virt/kvm/kvmmain.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value.
Other sources
In several functions vcpuid is used as an offset into rtcstatus.destmap in order to set or clear bits in kernel memory, potentially leading to out-of-bound access when vcpuid is larger than 255.
An unprivileged local user could use this flaw to elevate their privileges on the system.
