CVE-2024-27406

A vulnerability was found and fixed in the Linux kernel's TESTIOVITER configuration option. This fix corrected the dependancy on the Memory Management Unit MMU. Previously, enabling this option without proper dependency checks could lead to kernel misbehavior or crashes. Mitigation Mitigation for...

UBUNTU-CVE-2024-35843

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Use device rbtree in iopf reporting path The existing I/O page fault handler currently locates the PCI device by calling pcigetdomainbusandslot. This function searches the list of all PCI devices until the desired...

UBUNTU-CVE-2024-27079

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix NULL domain on device release In the kdump kernel, the IOMMU operates in deferredattach mode. In this mode, info-domain may not yet be assigned by the time the releasedevice function is called. It leads to the...

DEBIAN-CVE-2024-26990

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Write-protect L2 SPTEs in TDP MMU when clearing dirty status Check kvmmmupageadneedwriteprotect when deciding whether to write-protect or clear D-bits on TDP MMU SPTEs, so that the TDP MMU accounts for any...

kernel: iommufd: IOMMUFD_DESTROY should not increase the refcount

A race condition was identified in the iommufd subsystem of the Linux kernel where the IOMMUFDDESTROY command incorrectly increments an object’s reference count without holding the expected exclusive synchronization destroyrwsem. This violates the assumption that temporary reference count...

OESA-2024-1356 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Don't advance iterator after restart due to yielding After dropping mmulock in the TDP MMU, restart the iterator during tdpiternext and do not...

ALPINE-CVE-2023-46839

PCI devices can make use of a functionality called phantom functions, that when enabled allows the device to generate requests using the IDs of functions that are otherwise unpopulated. This allows a device to extend the number of outstanding requests. Such phantom functions need an IOMMU context...

kernel: KVM: x86/mmu: race condition in direct_page_fault()

A flaw was found in the Linux kernel in the KVM. A race condition in directpagefault allows guest OS users to cause a denial of service host OS crash or host OS memory corruption when nested virtualization and the TDP MMU are enabled...

SUSE CVE-2021-47094

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Don't advance iterator after restart due to yielding After dropping mmulock in the TDP MMU, restart the iterator during tdpiternext and do not advance the iterator. Advancing the iterator results in skipping the...

CVE-2023-52559
