CVE-2009-3638

Publication date 29 October 2009

Last updated 24 July 2024


Ubuntu priority

Integer overflow in the kvm_dev_ioctl_get_supported_cpuid function in arch/x86/kvm/x86.c in the KVM subsystem in the Linux kernel before 2.6.31.4 allows local users to have an unspecified impact via a KVM_GET_SUPPORTED_CPUID request to the kvm_arch_dev_ioctl function.

From the Ubuntu Security Team

David Wagner discovered that KVM did not correctly bounds-check CPUID entries. A local attacker could exploit this to crash the system or possibly gain elevated privileges. Ubuntu 6.06 and 9.10 were not affected.
