PT-2025-30853
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the bnxt en module of the Linux kernel related to DMA unmapping when transmitting XDP REDIRECT packets. Specifically, the dma unmap len set function was called with an...
PT-2026-8126
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel related to IOMMU and stale IOTLB entries within the kernel address space. The issue involves the need to invalidate IOTLB paging cache entries before...
OESA-2024-2550 linux-firmware security update
This package contains firmware images required by some devices. Security Fixes: IOMMU improperly handles certain special address ranges with invalid device table entries DTEs, which may allow an attacker with privileges and a compromised Hypervisor to induce DTE faults to bypass RMP checks in...
The vulnerabilities of the iommu/vt-d components of the Linux operating system’s kernel, which allow a hacker to cause a service failure
The vulnerability of the iommu/vt-d components in the Linux operating system’s kernel is related to the lack of memory release after the effective lifespan of these components has ended. Exploiting this vulnerability can allow an attacker to cause a service failure...
The vulnerability of the powerpc/pseries/iommu components in the Linux operating system allows a hacker to cause a service failure.
