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...

Security update for xen (important)

This updates xen to version 4.4.406 to fix the following issues: - An unprivileged user in a guest could gain guest could escalate privilege to that of the guest kernel, if it had could invoke the instruction emulator. Only 64-bit x86 HVM guest were affected. Linux guest have not been vulnerable...

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...

Researchers Question Security in AMD's Upcoming Zen Chips

As more computing heads to the clouds, security researchers are questioning the security of virtual machine control panels called hypervisors. One of the first hardware-based solutions to address these concerns will be deployed by chip manufacturer AMD, called Secure Encrypted Virtualization. The...

FreeBSD : xen-kernel -- x86 null segments not always treated as unusable (50ac2e96-ba4d-11e6-ae1b-002590263bf5)

The Xen Project reports : The Xen x86 emulator erroneously failed to consider the unusability of segments when performing memory accesses. The intended behaviour is as follows: The user data segment %ds, %es, %fs and %gs selectors may be NULL in 32-bit to prevent access. In 64-bit, NULL has a...
