Deadlock in x86 HVM standard VGA handling

ISSUE DESCRIPTION The hypervisor contains code to accelerate VGA memory accesses for HVM guests, when the virtual VGA is in "standard" mode. Locking involved there has an unusual discipline, leaving a lock acquired past the return from the function that acquired it. This behavior results in a...

Name of the Vulnerable Software and Affected Versions Xen hypervisor versions prior to 4.7 Description The issue is related to the hypervisor's code for accelerating VGA memory accesses for HVM guests in "standard" mode. The locking mechanism involved has an unusual discipline, which can lead to ...

x86: Deadlock in vlapic_error()

ISSUE DESCRIPTION In x86's APIC Advanced Programmable Interrupt Controller architecture, error conditions are reported in a status register. Furthermore, the OS can opt to receive an interrupt when a new error occurs. It is possible to configure the error interrupt with an illegal vector, which...

The vulnerability of the x86 HVM Hypercall Handler component of the cross-platform hypervisor Xen in the Linux operating system allows a attacker to trigger a service failure.

The vulnerability of the x86 HVM Hypercall Handler component in the cross-platform hypervisor Xen for Linux operating systems is related to the ability to freely switch between 64-bit and other system modes. Exploiting this vulnerability could allow an attacker to trigger a service failure...

CVE-2023-46842

The Xen hypervisor is vulnerable to a crash due to a flaw in hypercall processing for HVM guests that can switch between 64-bit and other modes. The root cause is that internal sanity checking of translated hypercall arguments incorrectly assumes the high halves of registers are always clear. Whe...
