Linux Distros Unpatched Vulnerability : CVE-2024-45818

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

Internet Bug Bounty: Deadlock in x86 HVM standard VGA handling

The Xen hypervisor contained a vulnerability in its handling of standard VGA memory accesses for HVM guests. The locking mechanism used had an unusual discipline that could lead to a deadlock when emulating an instruction with two memory accesses to VGA memory. The vulnerability was acknowledged ...

Qemu: cirrus: OOB access issue in mode4and5 write functions

Quick emulator QEMU, compiled with the Cirrus CLGD 54xx VGA Emulator support, is vulnerable to an OOB write access issue. The issue could occur while writing to VGA memory via mode4and5 write functions. A privileged user inside guest could use this flaw to crash the QEMU process resulting in Deni...

QEMU: Banked access to VGA memory (VBE) uses inconsistent bounds checks

ISSUE DESCRIPTION Qemu VGA module allows banked access to video memory using the window at 0xa00000 and it supports different access modes with different address calculations. But an attacker can easily change access modes after setting the bank register. This is CVE-2016-3710. Qemu VGA module...
