Detail
| The do_insn_fetch function in arch/x86/kvm/emulate.c in the x86 emulator in the KVM subsystem in the Linux kernel before 2.6.32-rc8-next-20091125 tries to interpret instructions that contain too many bytes to be valid, which allows guest OS users to cause a denial of service (increased scheduling latency) on the host OS via unspecified manipulations related to SMP support. |

| Title: | DSA-1962 kvm -- several vulnerabilities | ||
| Description: | Several vulnerabilities have been discovered in kvm, a full virtualization system. The Common Vulnerabilities and Exposures project identifies the following problems: It was discovered an Integer overflow in the kvm_dev_ioctl_get_supported_cpuid function. This allows local users to have an unspecified impact via a KVM_GET_SUPPORTED_CPUID request to the kvm_arch_dev_ioctl function. It was discovered that the handle_dr function in the KVM subsystem does not properly verify the Current Privilege Level before accessing a debug register, which allows guest OS users to cause a denial of service on the host OS via a crafted application. It was discovered that the do_insn_fetch function in the x86 emulator in the KVM subsystem tries to interpret instructions that contain too many bytes to be valid, which allows guest OS users to cause a denial of service on the host OS via unspecified manipulations related to SMP support. | ||
