DEBIAN-CVE-2026-53281

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Avoid NULL pointer dereference or refcount corruption Commit 60f030f7418d "iommu/vt-d: Avoid use of NULL after WARNONONCE" fixed a NULL pointer dereference in an unlikely situation partly. If devpasid is not found in...

EUVD-2026-39847

In the Linux kernel, the following vulnerability has been resolved: iommu/riscv: Remove overflows on the invalidation path Since RISC-V supports a sign extended page table it should support a gather-end of ULONGMAX, but if this happens it will infinite loop because of the overflow. Also avoid...

CVE-2026-53312

The CVE-2026-53312 issue affects the Linux kernel in the iommu/riscv invalidation path. The root cause is integer overflow when handling sign-extended page tables (ULONG_MAX) that could lead to an infinite loop during invalidation. The patch removes these overflows and relocates the +1 to avoid l...

CVE-2026-53283

CVE-2026-53283 covers a bounds-check failure in the Linux kernel AMD IOMMU path. The issue arises in __rlookup_amd_iommu(): rlookup_table[devid] is indexed without an internal bounds check, and iommu_device_register() iterates all PCI devices, calling amd_iommu_probe_device() for each. If a devic...

CVE-2026-53281

The CVE-2026-53281 entries describe a Linux kernel IOMMU VT-d issue where NULL pointer dereference or refcount corruption could occur during teardown if dev_pasid was not found in the dev_pasids list or if domain was never attached. The root cause was improper teardown execution after potential N...

CVE-2026-53280

The CVE-2026-53280 issue affects the Linux kernel IOMMU path. A NULL group->domain could be dereferenced in pci_dev_reset_iommu_done() when a default domain fails to allocate during the first probe, potentially causing a crash at domain->ops->attach_dev invoked by __iommu_attach_device()...

CVE-2026-53053

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit AMD driver. The clonealias function incorrectly uses the device ID devid when handling alias devices. This can lead to the propagation of wrong or stale Device Table Entry DTE entries to alias devices, potentially...

EUVD-2026-39338

In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Fix truncation for block sizes = 4G When the iommu is used the linearization of the mapping can give a single block that is very large split across multiple SG entries. When rdmablockiternext reassembles the split SG...

CVE-2026-53164

The CVE-2026-53164 issue in the Linux kernel affects the iommu/dma path, specifically swiotlb handling of mappings in iommu_dma_iova_link_swiotlb(). When a mapping is unaligned, the middle segment may be empty and a 0-size call to iommu_map() occurs, which the iommupt implementation treats as ill...

In the Linux kernel, the following vulnerability has been resolved: iommu/dma: Do not try to iommumap a 0 length region in swiotlb iommudmaiovalinkswiotlb processes a mapping that is unaligned in three parts, the head, middle and trailer. If the middle is empty because there are no aligned pages ...
