CVE-2012-4461
Last modified
CVE-2012-4461 is a vulnerability of currently unknown severity. The KVM subsystem in the Linux kernel before 3.6.9, when running on hosts that use qemu userspace without XSAVE, allows local users to cause a denial of service (kernel OOPS) by using the KVM_SET_SREGS ioctl to set the X86_CR4_OSXSAVE bit in the guest cr4 register, then calling the KVM_RUN ioctl.. EPSS estimates a 0.36% chance of exploitation in the next 30 days.
