qemu: insufficient constraints checking in exec.c:subpage_register()
The subpage MMIO initialization functionality in the subpageregister function in exec.c in QEMU-KVM, as used in the Hypervisor aka rhev-hypervisor in Red Hat Enterprise Virtualization RHEV 2.2 and KVM 83, does not properly select the index for access to the callback array, which allows guest OS...
CVE-2010-0730
The MMIO instruction decoder in the Xen hypervisor in the Linux kernel 2.6.18 in Red Hat Enterprise Linux RHEL 5 allows guest OS users to cause a denial of service 32-bit guest OS crash via vectors that trigger an unspecified instruction emulation...
CVE-2010-0730
CVE-2010-0730 is a vulnerability in the MMIO instruction decoder of the Xen hypervisor within the Linux kernel 2.6.18 used by RHEL5. The flaw allows an unprivileged guest OS user to trigger an instruction emulation path and cause a denial-of-service (32-bit guest crash). The issue is documented a...
xen: emulator instruction decoding inconsistency
The MMIO instruction decoder in the Xen hypervisor in the Linux kernel 2.6.18 in Red Hat Enterprise Linux RHEL 5 allows guest OS users to cause a denial of service 32-bit guest OS crash via vectors that trigger an unspecified instruction emulation...
Design/Logic Flaw
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...
CVE-2010-0419
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...

kvm: emulator privilege escalation segment selector check
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...
Design/Logic Flaw
The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing SMP, does not use the Current Privilege Level CPL and I/O Privilege Level IOPL to restrict instruction execution, which allows guest OS users to cause a denial of service guest OS crash or gain privileges on the...
Design/Logic Flaw
The x86 emulator in KVM 83 does not use the Current Privilege Level CPL and I/O Privilege Level IOPL in determining the memory access available to CPL3 code, which allows 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...
CVE-2010-0306
The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing SMP, does not use the Current Privilege Level CPL and I/O Privilege Level IOPL to restrict instruction execution, which allows guest OS users to cause a denial of service guest OS crash or gain privileges on the...
CVE-2010-0306
The connected MiracleLinux AXSA advisory references CVE-2010-0306, describing a vulnerability in the KVM x86 emulator: when a guest is SMP-configured, CPL/IOPL checks are not applied to memory access for CPL3 code. This allows guest OS users to crash the guest or potentially gain privileges by ab...
