Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from a mapping disclosure vulnerability in MMIO...
DEBIAN-CVE-2021-47060
In the Linux kernel, the following vulnerability has been resolved: KVM: Stop looking for coalesced MMIO zones if the bus is destroyed Abort the walk of coalesced MMIO zones if kvmiobusunregisterdev fails to allocate memory for the new instance of the bus. If it can't instantiate a new bus,...
kernel: SEV-ES local priv escalation
A buffer overflow and null pointer dereference flaw was found in the Linux kernel's Secure Encrypted Virtualization SEV implementation for AMD functionality. This issue occurs when a user in SEV guest VM accesses MMIO registers, which could allow a local user to crash the system or escalate their...
Researchers Find 34 Windows Drivers Vulnerable to Full Device Takeover
As many as 34 unique vulnerable Windows Driver Model WDM and Windows Driver Frameworks WDF drivers could be exploited by non-privileged threat actors to gain full control of the devices and execute arbitrary code on the underlying systems. "By exploiting the drivers, an attacker without privilege...

AZL-35159 CVE-2022-2962 affecting package qemu for versions less than 6.2.0-18
A DMA reentrancy issue was found in the Tulip device emulation in QEMU. When Tulip reads or writes to the rx/tx descriptor or copies the rx/tx frame, it doesn't check whether the destination address is its own MMIO address. This can cause the device to trigger MMIO handlers multiple times, possib...
CVE-2022-21233
A flaw was found in hw. The APIC can operate in xAPIC mode also known as a legacy mode, in which APIC configuration registers are exposed through a memory-mapped I/O MMIO page. This flaw allows an attacker who can execute code on a target CPU to query the APIC configuration page. When reading the...
Intel® Processors MMIO Undefined Access Advisory
Summary: A potential security vulnerability in Memory Mapped I/O MMIO for some 14nm Client/Xeon E3 Intel® Processors may allow a denial of service in certain virtualized environments. Vulnerability Details: CVEID: CVE-2022-21180 Description: Improper input validation for some Intel® Processors ma...
QEMU: net: e1000e: use-after-free while sending packets
A use-after-free flaw was found in the INTEL 82574 NIC e1000e emulator of the QEMU. The issue happens while sending packets if the guest user has set the packet data address to the e1000e's MMIO address. This flaw allows a guest user or process to crash the QEMU process on the host, resulting in ...
PT-2021-8177
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The issue is related to the clk component of the Linux kernel, where unbinding a CCU driver unmaps the device's MMIO region but leaves its clocks/resets and their providers registered...
Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario
A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the...

UBUNTU-CVE-2020-12829
In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPYAREA macro while handling MMIO write operations through the sm5012denginewrite callback. A local attacker could abuse this flaw to crash the QEMU process in sm5012doperatio...
hw: Intel GPU Denial Of Service while accessing MMIO in lower power state
A flaw was found in Intel graphics hardware GPU where a local attacker with the ability to issue an ioctl could trigger a hardware level crash if MMIO registers were read while the graphics card was in a low-power state. This creates a denial of service situation and the GPU and connected display...
