CVE-2012-4461

CVE-2012-4461 overview: The Linux kernel KVM subsystem (pre-3.6.9) on hosts using qemu userspace without XSAVE is vulnerable. A local attacker can trigger a denial of service (kernel OOPS) by calling KVM_SET_SREGS to enable the X86_CR4_OSXSAVE bit in the guest CR4, then issuing KVM_RUN. The conne...
