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...

kernel: ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattr

In the Linux kernel, the following vulnerability has been resolved: ima: don't clear IMADIGSIG flag when setting or removing non-IMA xattr Currently when both IMA and EVM are in fix mode, the IMA signature will be reset to IMA hash if a program first stores IMA signature in security.ima and then...

DeepFake Forensics AI: A Multi-Modal Detection and Blockchain-Anchored Evidence Management Platform

The proliferation of AI-generated synthetic media poses a critical threat to the integrity of digital evidence in legal and forensic contexts. Existing deepfake detection systems typically address a single modality and provide no mechanism for tamper-proof evidence preservation. We present DeepFa...
