Races in the grant table unmap code

ISSUE DESCRIPTION We have discovered two bugs in the code unmapping grant references. When a grant had been mapped twice by a backend domain, and then unmapped by two concurrent unmap calls, the frontend may be informed that the page had no further mappings when the first call completed rather th...

x86: PKRU and BND* leakage between vCPU-s

ISSUE DESCRIPTION Memory Protection Extensions MPX and Protection Key PKU are features in newer processors, whose state is intended to be per-thread and context switched along with all other XSAVE state. Xen's vCPU context switch code would save and restore the state only if the guest had set the...

NULL pointer deref in event channel poll

ISSUE DESCRIPTION When polling event channels, in general arbitrary port numbers can be specified. Specifically, there is no requirement that a polled event channel ports has ever been created. When the code was generalised from an earlier implementation, introducing some intermediate pointers, a...

stale P2M mappings due to insufficient error checking

ISSUE DESCRIPTION Certain actions require removing pages from a guest's P2M Physical-to-Machine mapping. When large pages are in use to map guest pages in the 2nd-stage page tables, such a removal operation may incur a memory allocation to replace a large mapping with individual smaller ones. If...

page transfer may allow PV guest to elevate privilege

ISSUE DESCRIPTION Domains controlling other domains are permitted to map pages owned by the domain being controlled. If the controlling domain unmaps such a page without flushing the TLB, and if soon after the domain being controlled transfers this page to another PV domain via GNTTABOPtransfer o...

ARM guest disabling interrupt may crash Xen

ISSUE DESCRIPTION Virtual interrupt injection could be triggered by a guest when sending an SGI e.g IPI to any vCPU or by configuring timers. When the virtual interrupt is masked, a missing check in the injection path may result in reading invalid hardware register or crashing the host. IMPACT A...

arm: vgic: Out-of-bound access when sending SGIs

ISSUE DESCRIPTION ARM guests can send SGI i.e. IPI targeting a list of vCPUs using the MMIO register GICDSGIR GICv2 or System Register ICCSGI1R GICv3. However, the emulation code does not sanitize the list and will directly access an array without checking whether the array index is within bounds...
