The vulnerability of the ARM System Memory Management Unit (SMMU) in NVIDIA Jetson TX2 processors allows a hacker to cause a system failure.

The vulnerability of the ARM System Memory Management Unit SMMU on NVIDIA Jetson TX2 processors lies in insufficient checking of exception states. Exploiting this vulnerability can allow attackers to cause system failures...

UBUNTU-CVE-2021-27379

An issue was discovered in Xen through 4.11.x, allowing x86 Intel HVM guest OS users to achieve unintended read/write DMA access, and possibly cause a denial of service host OS crash or gain privileges. This occurs because a backport missed a flush, and thus IOMMU updates were not always correct...

ALPINE-CVE-2020-27670

An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a denial of service data corruption, cause a data leak, or possibly gain privileges because an AMD IOMMU page-table entry can be half-updated...

UBUNTU-CVE-2020-27670

An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a denial of service data corruption, cause a data leak, or possibly gain privileges because an AMD IOMMU page-table entry can be half-updated...

UBUNTU-CVE-2020-27671

An issue was discovered in Xen through 4.14.x allowing x86 HVM and PVH guest OS users to cause a denial of service data corruption, cause a data leak, or possibly gain privileges because coalescing of per-page IOMMU TLB flushes is mishandled...

ALPINE-CVE-2020-15565

An issue was discovered in Xen through 4.13.x, allowing x86 Intel HVM guest OS users to cause a host OS denial of service or possibly gain privileges because of insufficient cache write-back under VT-d. When page tables are shared between IOMMU and CPU, changes to them require flushing of both...

A flaw was found in the way Intel CPUs handle inconsistency between, virtual to physical memory address translations in CPU's local cache and system software's Paging structure entries. A privileged guest user may use this flaw to induce a hardware Machine Check Error on the host processor,...

ALPINE-CVE-2019-19577

An issue was discovered in Xen through 4.12.x allowing x86 AMD HVM guest OS users to cause a denial of service or possibly gain privileges by triggering data-structure access during pagetable-height updates. When running on AMD systems with an IOMMU, Xen attempted to dynamically adapt the number ...
