Search: CVE-2025-71089

CVE-2025-71089 is a high-severity vulnerability in the Linux kernel affecting version 5.2. It involves the IOMMU Shared Virtual Addressing (SVA) feature on x86 architectures, where the IOMMU hardware caches kernel page table entries without proper notification when these pages are freed and reused. This can lead to use-after-free and write-after-free conditions, potentially allowing privilege escalation or data corruption. The vulnerability is addressed by disabling SVA on x86 until a safe notification mechanism is implemented to flush IOMMU caches before freeing kernel page table pages.
