Linux Distros Unpatched Vulnerability : CVE-2020-15852
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An issue was discovered in the Linux kernel 5.5 through 5.7.9, as used in Xen through 4.13.x for x86 PV guests. An attacker may be granted the I/O port...
The x86 emulator in KVM 83 does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) in determining the memory access available to CPL3 code which allows guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region a related issue to CVE-2010-0306.

Xen Linux kernel privilege control vulnerability
Linux kernel is the kernel used by Linux, an open source operating system released by the Linux Foundation in the U.S. Xen is an open source virtual machine monitor product from the University of Cambridge, UK. The product enables different and incompatible operating systems to run on the same...
CVE-2020-12446
The ene.sys driver in G.SKILL Trident Z Lighting Control through 1.00.08 exposes mapping and un-mapping of physical memory, reading and writing to Model Specific Register MSR registers, and input from and output to I/O ports to local non-privileged users. This leads to privilege escalation to NT...
CVE-2018-18536
The GLCKIo and Asusgio low-level drivers in ASUS Aura Sync v1.07.22 and earlier expose functionality to read/write data from/to IO ports. This could be leveraged in a number of ways to ultimately run code with elevated privileges...
CVE-2018-19322
The GPCIDrv and GDrv low-level drivers in GIGABYTE APP Center v1.05.21 and earlier, AORUS GRAPHICS ENGINE before 1.57, XTREME GAMING ENGINE before 1.26, and OC GURU II v2.08 expose functionality to read/write data from/to IO ports. This could be leveraged in a number of ways to ultimately run cod...
CVE-2018-10712
The AsrDrv101.sys and AsrDrv102.sys low-level drivers in ASRock RGBLED before v1.0.35.1, A-Tuning before v3.0.210, F-Stream before v3.0.210, and RestartToUEFI before v1.0.6.2 expose functionality to read/write data from/to IO ports. This could be leveraged in a number of ways to ultimately run co...
qemu: incorrect banked access bounds checking in vga module
An out-of-bounds read/write access flaw was found in the way QEMU's VGA emulation with VESA BIOS Extensions VBE support performed read/write operations using I/O port methods. A privileged guest user could use this flaw to execute arbitrary code on the host with the privileges of the host's QEMU...
kernel: kvm: reporting emulation failures to userspace
It was found that reporting emulation failures to user space could lead to either a local CVE-2014-7842 or a L2-L1 CVE-2010-5313 denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain...

DEBIAN-CVE-2016-3157
The switchto function in arch/x86/kernel/process64.c in the Linux kernel does not properly context-switch IOPL on 64-bit PV Xen guests, which allows local guest OS users to gain privileges, cause a denial of service guest OS crash, or obtain sensitive information by leveraging I/O port access...
kvm: emulator privilege escalation segment selector check
The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing SMP, does not properly restrict writing of segment selectors to segment registers, which might allow guest OS users to cause a denial of service guest OS crash or gain privileges on the guest OS by leveraging...
kvm: emulator privilege escalation IOPL/CPL level check
The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing SMP, does not use the Current Privilege Level CPL and I/O Privilege Level IOPL to restrict instruction execution, which allows guest OS users to cause a denial of service guest OS crash or gain privileges on the...
kvm: cat /dev/port in guest cause the host hang
The pitioportread function in the Programmable Interval Timer PIT emulation in i8254.c in KVM 83 does not properly use the pitstate data structure, which allows guest OS users to cause a denial of service host OS crash or hang by attempting to read the /dev/port file...
