CVE-2011-4622 (GCVE-0-2011-4622)

Vulnerability from nvd – Published: 2012-01-27 15:00 – Updated: 2024-08-07 00:09
VLAI?
Summary
The create_pit_timer function in arch/x86/kvm/i8254.c in KVM 83, and possibly other versions, does not properly handle when Programmable Interval Timer (PIT) interrupt requests (IRQs) when a virtual interrupt controller (irqchip) is not available, which allows local users to cause a denial of service (NULL pointer dereference) by starting a timer.
Severity ?
No CVSS data available.

CVE-2010-2784 (GCVE-0-2010-2784)

Vulnerability from nvd – Published: 2010-08-24 17:00 – Updated: 2024-08-07 02:46
VLAI?
Summary
The subpage MMIO initialization functionality in the subpage_register 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 users to cause a denial of service (guest OS crash) or possibly gain privileges via unspecified vectors.
Severity ?
No CVSS data available.

VLAI?
Summary
QEMU-KVM, as used in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and KVM 83, does not properly validate guest QXL driver pointers, which allows guest OS users to cause a denial of service (invalid pointer dereference and guest OS crash) or possibly gain privileges via unspecified vectors.
Severity ?

CVE-2011-4622 (GCVE-0-2011-4622)

Vulnerability from cvelistv5 – Published: 2012-01-27 15:00 – Updated: 2024-08-07 00:09
VLAI?
Summary
The create_pit_timer function in arch/x86/kvm/i8254.c in KVM 83, and possibly other versions, does not properly handle when Programmable Interval Timer (PIT) interrupt requests (IRQs) when a virtual interrupt controller (irqchip) is not available, which allows local users to cause a denial of service (NULL pointer dereference) by starting a timer.
Severity ?
No CVSS data available.
