CVE-2015-4104

Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service unexpected interrupt and host crash via unspecified vectors...

CVE-2015-4105

Xen 3.3.x through 4.5.x enables logging for PCI MSI-X pass-through error messages, which allows local x86 HVM guests to cause a denial of service host disk consumption via certain invalid operations...

UBUNTU-CVE-2015-4103

Xen 3.3.x through 4.5.x does not properly restrict write access to the host MSI message data field, which allows local x86 HVM guest administrators to cause a denial of service host interrupt handling confusion via vectors related to qemu and accessing spanning multiple fields...

PCI MSI mask bits inadvertently exposed to guests

ISSUE DESCRIPTION The mask bits optionally available in the PCI MSI capability structure are used by the hypervisor to occasionally suppress interrupt delivery. Unprivileged guests were, however, nevertheless allowed direct control of these bits. IMPACT Interrupts may be observed by Xen at...

Guest triggerable qemu MSI-X pass-through error messages

ISSUE DESCRIPTION Device model code dealing with guest PCI MSI-X interrupt management activities logs messages on certain supposedly invalid guest operations. IMPACT A buggy or malicious guest repeatedly invoking such operations may result in the host disk to fill up, possibly leading to a Denial...

Potential unintended writes to host MSI message data field via qemu

ISSUE DESCRIPTION Logic is in place to avoid writes to certain host config space fields when the guest must nevertheless be able to access their virtual counterparts. A bug in how this logic deals with accesses spanning multiple fields allows the guest to write to the host MSI message data field...

The HVMOPinjectmsi function in Xen 4.2.x, 4.3.x, and 4.4.x does not properly check the return value from the IRQ setup check, which allows local HVM guest administrators to cause a denial of service NULL pointer dereference and crash via unspecified vectors...

CVE-2013-3495

The Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x allows local guests to cause a denial of service kernel panic via a malformed Message Signaled Interrupt MSI from a PCI device that is bus mastering capable that triggers a System Error Reporting SERR Non-Maskable Interrupt NMI...

CVE-2013-3495

CVE-2013-3495 affects the Intel VT-d Interrupt Remapping engine in Xen 3.3.x through 4.3.x. The vulnerability allows a local guest to cause a denial of service (kernel panic) by sending a malformed Message Signaled Interrupt (MSI) from a bus-master PCI device, triggering a System Error Reporting ...

Intel VT-d Interrupt Remapping engines can be evaded by native NMI interrupts

ISSUE DESCRIPTION Message Signaled Interrupts MSI interrupts on Intel platforms are defined as DWORD writes to a special address location 0xFEE?????. MSIs on Intel Platforms supporting VT-d have two defined formats - Remappable format interrupts, and Compatibility not remappable format interrupts...
