CVE-2014-3646

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel through 3.17.2 does not have an exit handler for the INVVPID instruction, which allows guest OS users to cause a denial of service guest OS crash via a crafted application...

CVE-2014-3645

CVE-2014-3645 affects the Linux kernel KVM implementation in arch/x86/kvm/vmx.c, with versions before 3.12. The root cause is that the code path handling the INVEPT instruction lacks an exit handler, which can allow a guest OS user to trigger a denial of service by crashing the guest via a crafte...

CVE-2014-3611

CVE-2014-3611 corresponds to a race condition in the Linux kernel’s KVM PIT emulation: the __kvm_migrate_pit_timer function in arch/x86/kvm/i8254.c, with affected versions up to and including 3.17.2. The vulnerability allows a guest OS user to trigger a host OS crash via incorrect PIT emulation. ...

CVE-2014-3610

The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service host OS crash by leveraging guest OS privileges, relate...

CVE-2014-8481

The instruction decoder in arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel before 3.18-rc2 does not properly handle invalid instructions, which allows guest OS users to cause a denial of service NULL pointer dereference and host OS crash via a crafted application that triggers 1 a...

CVE-2014-3647

CVE-2014-3647 affects the Linux kernel KVM emulation path: arch/x86/kvm/emulate.c. The root cause is improper handling of RIP changes during instruction emulation, enabling a local guest OS user to crash the guest (DoS) with a crafted application in kernels up to 3.17.2. The provided connected do...

CVE-2014-8480

CVE-2014-8480 affects the Linux kernel KVM subsystem: the instruction decoder in arch/x86/kvm/emulate.c lacks intended decoder-table flags for certain RIP-relative instructions. This can allow a guest OS user to trigger a NULL pointer dereference and crash the host OS (denial of service). The vul...

CVE-2014-8481

CVE-2014-8481 affects the Linux kernel KVM arch/x86/kvm/emulate.c; the instruction decoder mishandles invalid instructions, allowing guest OS users to trigger a NULL pointer dereference and host crash via a crafted application that either fetches an invalid instruction or uses too many bytes. Roo...

CVE-2014-3690

arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service system disruption by...

CVE-2014-3647

arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service guest OS crash via a crafted application...
