CVE-2023-52658

Description

CVE-2023-52658 is a vulnerability in the Linux kernel's Mellanox MLX5 driver, specifically related to the switchdev mode. A previous commit intended to block entering switchdev mode due to namespace inconsistencies inadvertently caused system crashes. To address this, the problematic commit was reverted, restoring stability. Users should update their Linux kernel to a version that includes this reversion to ensure reliable operation.

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).
