xen-kernel -- leak of main per-domain vcpu pointer array

The Xen Project reports: A domain's primary array of vcpu pointers can be allocated by a toolstack exactly once in the lifetime of a domain via the XENDOMCTLmaxvcpus hypercall. This array is leaked on domain teardown. This memory leak could -- over time -- exhaust the host's memory. A domain give...

Mishandling of uninitialised FIFO-based event channel control blocks

ISSUE DESCRIPTION When using the FIFO-based event channels, there are no checks for the existence of a control block when binding an event or moving it to a different VCPU. This is because events may be bound when the ABI is in 2-level mode e.g., by the toolstack before the domain is started. The...

CVE-2014-5149

CVE-2014-5149 affects Xen 4.2.x–4.4.x when using shadow pagetables. Certain MMU virtualization operations are not preemptible, allowing a local HVM guest to trigger a denial of service by processing every page assigned to the guest (vcpu consumption). This is described as a different vulnerabilit...

CVE-2014-5146 affects Xen 4.2.x–4.4.x before the xsa97-hap patch. When using Hardware Assisted Paging (HAP), certain MMU virtualization ops are not preemptible, allowing a local HVM guest to trigger a DoS by consuming all vCPUs for pages assigned to the guest. It is described as a separate issue ...
