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-2014-3611

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

CVE-2014-3610 is a Linux kernel KVM WRMSR emulation flaw present up to and including 3.17.2. The issue arises when guest writes a non-canonical value to a model-specific register, causing the host to crash (DoS). It is tied to wrmsr_interception (arch/x86/kvm/svm.c) and handle_wrmsr (arch/x86/kvm...

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-2014-3647

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-2014-3690

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-2014-8480

The instruction decoder in arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel before 3.18-rc2 lacks intended decoder-table flags for certain RIP-relative instructions, which allows guest OS users to cause a denial of service NULL pointer dereference and host OS crash via a crafted...
