Linux kernel security vulnerabilities

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 the addition of a disable/clear MSIX privilege entry on device shutdown to mirror the MSIX entry enabled on...

SUSE CVE-2013-1952

Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service interrupt injection via unspecified vector...

SUSE CVE-2017-15590

An issue was discovered in Xen through 4.9.x allowing x86 guest OS users to cause a denial of service hypervisor crash or possibly gain privileges because MSI mapping was mishandled...

PT-2025-49671

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The irdma driver within the Linux kernel could use a number of MSIX vectors exceeding the number of online CPUs plus one. This resulted in a kernel warning when attempting to update the...

UBUNTU-CVE-2021-3308

An issue was discovered in Xen 4.12.3 through 4.12.4 and 4.13.1 through 4.14.x. An x86 HVM guest with PCI pass through devices can force the allocation of all IDT vectors on the system by rebooting itself with MSI or MSI-X capabilities enabled and entries setup. Such reboots will leak any vectors...

DEBIAN-CVE-2016-7466

Memory leak in the usbxhciexit function in hw/usb/hcd-xhci.c in QEMU aka Quick Emulator, when the xhci uses msix, allows local guest OS administrators to cause a denial of service memory consumption and possibly QEMU process crash by repeatedly unplugging a USB device...

UBUNTU-CVE-2015-8554

Buffer overflow in hw/pt-msi.c in Xen 4.6.x and earlier, when using the qemu-xen-traditional aka qemu-dm device model, allows local x86 HVM guest administrators to gain privileges by leveraging a system with access to a passed-through MSI-X capable physical PCI device and MSI-X table entries,...

Xen Denial of Service Vulnerability (CNVD-2015-03572)

Xen is an open source virtual machine monitor. Xen versions 3.3.x-4.5.x, fail to properly restrict access to the PCI MSI mask bit, which can be exploited by native x86 HVM clients to cause a denial of service unexpected outage and host crash...

UBUNTU-CVE-2015-4104

Xen 3.3.x through 4.5.x does not properly restrict access to PCI MSI mask bits, which allows local x86 HVM guest users to cause a denial of service unexpected interrupt and host crash via unspecified vectors...
