一、漏洞信息
漏洞编号：CVE-2025-71089
漏洞归属组件：kernel
漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.12.33,6.4.0,6.6.0
CVSS评分：
BaseScore：7.8 High
Vector：CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
漏洞简述：
In the Linux kernel, a security vulnerability exists in the IOMMU Shared Virtual Addressing (SVA) feature. On x86 architecture when CONFIG_X86 is set, IOMMU hardware caches kernel page table entries. Due to the lack of notification mechanism for kernel page table changes, when kernel page table pages are freed and reused, the IOMMU may retain stale entries, leading to Use-After-Free (UAF) and Write-After-Free (WAF) conditions. This can be exploited to cause arbitrary physical memory DMA access or privilege escalation.

CVE-2025-71089

影响性分析说明：
In the Linux kernel, the following vulnerability has been resolved:

iommu: disable SVA when CONFIG_X86 is set

Patch series "Fix stale IOTLB entries for kernel address space", v7.

This proposes a fix for a security vulnerability related to IOMMU Shared
Virtual Addressing (SVA). In an SVA context, an IOMMU can cache kernel
page table entries. When a kernel page table page is freed and
reallocated for another purpose, the IOMMU might still hold stale,
incorrect entries. This can be exploited to cause a use-after-free or
write-after-free condition, potentially leading to privilege escalation or
data corruption.

This solution introduces a deferred freeing mechanism for kernel page
table pages, which provides a safe window to notify the IOMMU to
invalidate its caches before the page is reused.
