Xen Intel VMX hvmemul_vmfunc() NULL Pointer Dereference DoS (XSA-203)

According to its self-reported version number, the Xen hypervisor installed on the remote host is missing a security update. It is, therefore, affected by a NULL pointer dereference flaw due to a failure to utilize necessary NULL checks before doing indirect function calls through the hvmemulvmfu...

CVE-2016-10025

CVE-2016-10025 affects the Xen hypervisor when running on x86 with AMD SVM (VMFUNC emulation) and allows local HVM guests to crash the hypervisor due to a missing NULL pointer check in hvmemul_vmfunc(). Public references in the connected data show Xen versions 4.6.x–4.8.x as vulnerable and descri...

x86: missing NULL pointer check in VMFUNC emulation

ISSUE DESCRIPTION When support for the Intel VMX VMFUNC leaf 0 was added, a new optional function pointer hvmemulvmfunc was added to the hvmemulateops table. As is intended, that new function pointer is NULL on non-VMX hardware, including AMD SVM hardware. However at a call site, the necessary NU...

xen-kernel -- x86 task switch to VM86 mode mis-handled

The Xen Project reports: LDTR, just like TR, is purely a protected mode facility. Hence even when switching to a VM86 mode task, LDTR loading needs to follow protected mode semantics. This was violated by the code. On SVM AMD hardware: a malicious unprivileged guest process can escalate its...
