CVE-2026-52952

A flaw was found in the Linux kernel's Input/Output Memory Management Unit IOMMU subsystem, which manages how devices access system memory. A race condition, a situation where multiple operations occur in an unpredictable order, exists during device recovery when multiple memory domains are being...

CVE-2026-53057

A flaw was found in the Linux kernel, specifically within the Input/Output Memory Management Unit IOMMU for RISC-V architectures. This vulnerability occurs because the system does not properly clear out old memory translation information, known as Translation Lookaside Buffer TLB and context cach...

CVE-2026-53133

A flaw was found in the Linux kernel's RDMA/umem component. When the IOMMU Input/Output Memory Management Unit is used, a very large memory block can be split across multiple scatter-gather SG entries. During the reassembly of these split SG entries, an issue with truncation for block sizes great...

CVE-2026-53133

The CVE-2026-53133 entry concerns the Linux kernel RDMA/umem component where an IOMMU-assisted mapping can split a very large block across multiple SG entries. During reassembly in __rdma_block_iter_next(), 32-bit stack values can overflow, causing incorrect DMA addresses for blocks at or beyond ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: iommufd/selftest: A overflow issue was identified in IOMMUTESTOPADDRESERVED. syzkaller discovered that this could lead to an overflow in the test infrastructure and cause a WARN message by corrupting the reserved interval tree...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: genirq/msi: The IOMMU IOVA is now stored directly in the msidesc, rather than in the iommucookie. The process of translating MSI message addresses using IOMMU involved two steps, separated in time: 1 iommudmapreparemsi: A pointer...

kernel: iommu: disable SVA when CONFIG_X86 is set

A security vulnerability was found in the Linux kernel's IOMMU Shared Virtual Addressing SVA implementation on x86 architecture. When SVA is enabled, the IOMMU caches kernel page table entries. Since the kernel lacks a mechanism to notify the IOMMU when kernel page table pages are freed and...

CVE-2026-45862

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit virtualized directed I/O VT-d component. When a freshly allocated PASID Process Address Space ID table is written to a directory entry, the CPU cache flush for this table occurs too late. This creates a time window...

CVE-2026-45944

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit VT-d Virtualization Technology for Directed I/O component. When a context entry is being torn down, the 'Present' bit might not be cleared before other parts of the entry are zeroed. This can lead to the hardware...

UBUNTU-CVE-2026-45944

In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Clear Present bit before tearing down context entry When tearing down a context entry, the current implementation zeros the entire 128-bit entry using multiple 64-bit writes. This creates a window where the hardware c...
