CVE-2013-1796 WRITEUP WRITEUP
Linux Kernel < 3.8.4 - Memory Corruption via KVM MSR_KVM_SYSTEM_TIME Misalignment
The kvm_set_msr_common function in arch/x86/kvm/x86.c in the Linux kernel through 3.8.4 does not ensure a required time_page alignment during an MSR_KVM_SYSTEM_TIME operation, which allows guest OS users to cause a denial of service (buffer overflow and host OS memory corruption) or possibly have unspecified other impact via a crafted application.
CVE-2013-1797 WRITEUP WRITEUP
Linux Kernel < 3.8.4 - Use-After-Free in KVM MSR Handling
Use-after-free vulnerability in arch/x86/kvm/x86.c in the Linux kernel through 3.8.4 allows guest OS users to cause a denial of service (host OS memory corruption) or possibly have unspecified other impact via a crafted application that triggers use of a guest physical address (GPA) in (1) movable or (2) removable memory during an MSR_KVM_SYSTEM_TIME kvm_set_msr_common operation.
CVE-2013-1798 WRITEUP WRITEUP
Linux Kernel < 3.8.4 - Information Disclosure and Denial of Service via IOAPIC Register Operations
The ioapic_read_indirect function in virt/kvm/ioapic.c in the Linux kernel through 3.8.4 does not properly handle a certain combination of invalid IOAPIC_REG_SELECT and IOAPIC_REG_WINDOW operations, which allows guest OS users to obtain sensitive information from host OS memory or cause a denial of service (host OS OOPS) via a crafted application.
CVE-2013-4587 WRITEUP WRITEUP
Linux kernel <3.12.5 - Privilege Escalation
Array index error in the kvm_vm_ioctl_create_vcpu function in virt/kvm/kvm_main.c in the KVM subsystem in the Linux kernel through 3.12.5 allows local users to gain privileges via a large id value.
