Detail
| The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing (SMP), does not properly restrict writing of segment selectors to segment registers, which might allow guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, and replacing an instruction in between emulator entry and instruction fetch. |

| Title: | DSA-2010 kvm -- privilege escalation/denial of service | ||
| Description: | Several local vulnerabilities have been discovered in kvm, a full virtualization system. The Common Vulnerabilities and Exposures project identifies the following problems: Gleb Natapov discovered issues in the KVM subsystem where missing permission checks permit a user in a guest system to denial of service a guest or gain escalated privileges with the guest. Marcelo Tosatti fixed an issue in the PIT emulation code in the KVM subsystem that allows privileged users in a guest domain to cause a denial of service of the host system. Paolo Bonzini found a bug in KVM that can be used to bypass proper permission checking while loading segment selectors. This potentially allows privileged guest users to execute privileged instructions on the host system. | ||
