CVE-2009-4031

CVE-2009-4031 affects the KVM x86 emulator (arch/x86/kvm/emulate.c) in the Linux kernel prior to 2.6.32-rc8-next-20091125. The do_insn_fetch path could interpret instructions longer than valid, failing to enforce the 15-byte limit per instruction, which guest OS users can abuse to cause a denial ...
