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-2010-0309

The pitioportread function in the Programmable Interval Timer PIT emulation in i8254.c in KVM 83 does not properly use the pitstate data structure, which allows guest OS users to cause a denial of service host OS crash or hang by attempting to read the /dev/port file...

CVE-2010-0309

The CVE concerns the pit_ioport_read function in the PIT emulation (i8254.c) of KVM 83, where improper use of the pit_state data structure can be exploited by a guest to trigger a host denial-of-service (host crash or hang) by reading /dev/port. Affected component is KVM's PIT emulation; impact i...

CVE-2010-0298

Summary: CVE-2010-0298 affects the x86 emulator in KVM 83, where CPL/IOPL checks are not applied to CPL3 memory accesses, enabling a guest OS user to crash the guest or gain privileges via an IO port or MMIO region (related to CVE-2010-0306). What is affected: KVM/x86 emulator code in affected Li...

CVE-2010-0298
