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...

Kernel: s390: page table upgrade in secondary address mode may lead to privilege escalation

A flaw was found in the Linux kernel on s390 architecture. The issue occurs on multiprocessing systems when one s390 CPU is in Secondary Address Mode and another CPU does a kernel page table upgrade. An inter-processor interrupt IPI is then sent to each active CPU to update the control registers...

Linux kernel denial of service vulnerability (CNVD-2020-28264)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the drivers/spi/spi-dw.c file in Linux kernel versions prior to 5.4.17. An attacker can exploit this vulnerability to cause a denial...

UBUNTU-CVE-2020-12769

An issue was discovered in the Linux kernel before 5.4.17. drivers/spi/spi-dw.c allows attackers to cause a panic via concurrent calls to dwspiirq and dwspitransferone, aka CID-19b61392c5a8...

PT-2021-7351

Name of the Vulnerable Software and Affected Versions QEMU versions up to and including 4.2.0 Description The issue is related to an out-of-bounds heap buffer access in the ARM Generic Interrupt Controller emulator of QEMU.

kernel: powerpc: local user can read vector registers of other users' processes via an interrupt

A flaw in the Linux kernel on the PowerPC platform, was found where a local user can read vector registers of other user processes during a hardware interrupt. An attacker must start a transaction when the FPU operation begins or there is no leakage. Vector registers will become corrupted with...

Privilege Escalation

kernel is vulnerable to privilege escalation. The vulnerability exists using PCI passthrough without interrupt remapping support allowed KVM guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate thei...
