CVE-2024-35957
Description
CVE-2024-35957 is a vulnerability in the Linux kernel's Intel Virtualization Technology for Directed I/O (VT-d) subsystem. The issue stems from an incorrect assumption that each device has a unique source ID, leading to potential conflicts and system warnings during the IOMMU probe process. This flaw has been addressed by modifying the tracking mechanism to include only devices with PCI Address Translation Services (ATS) capabilities, thereby preventing unnecessary warnings and ensuring system stability. Users are advised to update their Linux kernel to a version that includes this fix to maintain optimal system performance.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
