CVE-2025-38298

Description

A flaw was found in the Linux kernel. A local user can trigger a denial of service by repeatedly loading and unloading the i10nm_edac module. This occurs because the adxl_component_count variable in the skx_edac_common module is not properly reset, leading to an out-of-bounds read in the ADXL component array. This out-of-bounds read causes a general protection fault, which results in a system crash and denial of service.

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).

The following CVSS metrics and score provided are preliminary and subject to review.
