CVE-2014-4022

The allocdomainstruct function in arch/arm/domain.c in Xen 4.4.x, when running on an ARM platform, does not properly initialize the structure containing the grant table pages for a domain, which allows local guest administrators to obtain sensitive information via the GNTTABOPsetuptable...

CVE-2014-3969

Xen 4.4.x, when running on an ARM system, does not properly check write permissions on virtual addresses, which allows local guest administrators to gain privileges via unspecified vectors...

CVE-2013-6282

The 1 getuser and 2 putuser API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against...

CVE-2014-2986

The vgicdistrmmiowrite function in the virtual guest interrupt controller GIC distributor arch/arm/vgic.c in Xen 4.4.x, when running on an ARM system, allows local guest users to cause a denial of service NULL pointer dereference and host crash via unspecified vectors...

CVE-2014-5148

Xen 4.4.x, when running on an ARM system and "handling an unknown system register access from 64-bit userspace," returns to an instruction of the trap handler for kernel space faults instead of an instruction that is associated with faults in 64-bit userspace, which allows local guest users to...

CVE-2014-5147

Xen 4.4.x, when running a 64-bit kernel on an ARM system, does not properly handle traps from the guest domain that use a different address width, which allows local guest users to cause a denial of service host crash via a crafted 32-bit process...

CVE-2011-1759

Integer overflow in the sysoabisemtimedop function in arch/arm/kernel/sysoabi-compat.c in the Linux kernel before 2.6.39 on the ARM platform, when CONFIGOABICOMPAT is enabled, allows local users to gain privileges or cause a denial of service heap memory corruption by providing a crafted argument...

x86: populate-on-demand balloon size inaccuracy can crash guests

ISSUE DESCRIPTION The design of the memory populate-on-demand PoD system requires that a guest's memory ballooning driver reach its memory reduction target. The target is not entirely well-defined in terms of the information visible to the appropriate parts of the system, so some unknown set of...

x86: Uncontrolled creation of large page mappings by PV guests

ISSUE DESCRIPTION The code to validate level 2 page table entries is bypassed when certain conditions are satisfied. This means that a PV guest can create writeable mappings using super page mappings. Such writeable mappings can violate Xen intended invariants for pages which Xen is supposed to...

x86: some pmu and profiling hypercalls log without rate limiting

ISSUE DESCRIPTION HYPERCALLxenoprofop and HYPERVISORxenpmuop log some errors and attempts at invalid operations. These log messages are not rate-limited, even though they can be triggered by guests. IMPACT A malicious guest could cause repeated logging to the hypervisor console, leading to a Deni...

arm: Race between domain destruction and memory allocation decrease

ISSUE DESCRIPTION While freeing the memory associated with a domain during domain destruction Xen could race with a toolstack domain reducing the amount of memory associated with that same domain via the XENMEMdecreasereservation. In the case where this race is hit the host will crash. The race i...

arm: various unimplemented hypercalls log without rate limiting

ISSUE DESCRIPTION The HYPERVISORphysdevop hypercall and most suboperations of the HYPERVISORhvmop hypercall are not currently implemented by Xen on ARM and when called will log the use to the hypervisor console. However these guest accessible log messages are not rate-limited. IMPACT A malicious...

arm: Host crash when preempting a multicall

ISSUE DESCRIPTION Early versions of Xen on ARM did not support "multicall" functionality the ability to perform multiple operations via a single hypercall and therefore stubbed out the functionality needed to support preemption of multicalls in a manner which crashed the host. When multicall...

x86: Long latency populate-on-demand operation is not preemptible

ISSUE DESCRIPTION When running an HVM domain in Populate-on-Demand mode, Xen would sometimes search the domain for memory to reclaim, in response to demands for population of other pages in the same domain. This search runs without preemption. The guest can, by suitable arrangement of its memory...
