CVE-2026-53133 RDMA/umem: Fix truncation for block sizes >= 4G

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-2026-53133

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 ...

This occurs during device recovery when multiple memor...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ptrace: The logic related to getdumpable has been made slightly more robust. The “dumpability” of a task essentially relates to the memory image of the task—the concept stems from whether the task can generate a core dump or not...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: KVM: arm64: Reassign the nestedmmus array to another location after mmulock The kvm-arch.nestedmmus array is processed under kvm-mmulock, including through the MMU notifier path kvmunmapgfnrange - kvmnesteds2unmap. This proces...

CVE-2026-34192

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an error path leading to UAF of GPU page tables. The vulnerability allows physical memory allocated for MMU page tables to be used after being freed. This was caused by an error path that would not...

CVE-2026-34192

CVE-2026-34192 affects GPU driver components (GPU DDK) where MMU page tables are freed without proper cleanup in an error path, allowing a non-privileged user to trigger use-after-free of physical memory. The issue is caused by _MMU_AllocLevel error recovery paths that leave dangling page table e...

CVE-2026-34192 GPU DDK - _MMU_AllocLevel error recovery paths leave dangling page table entries

Software installed and run as a non-privileged user may conduct improper GPU system calls to cause an error path leading to UAF of GPU page tables. The vulnerability allows physical memory allocated for MMU page tables to be used after being freed. This was caused by an error path that would not...

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-2026-10635 Dangling memory-domain pointer (use-after-free) in Xtensa MMU page-table code on memory-domain de-init

On Xtensa targets with CONFIGUSERSPACE and CONFIGXTENSAMMU, the page-table code arch/xtensa/core/ptables.c maintains a global list, xtensadomainlist, of active memory domains using a list node embedded inside the caller-owned struct kmemdomain. When a domain is destroyed via kmemdomaindeinit -...

CVE-2026-10635

CVE-2026-10635 affects Zephyr v4.4.0 on Xtensa targets with CONFIG_USERSPACE and CONFIG_XTENSA_MMU. The bug arises when destroying a memory domain via k_mem_domain_deinit(): the page-table code keeps a global xtensa_domain_list entry for the domain, but the node is not removed, leaving a dangling...
