CVE-2026-89461

Description

A flaw was found in the Linux kernel's max17040 power supply driver. A timing issue, known as a race condition, can occur during system suspend. This allows a background process (polling callback) to continue accessing the fuel gauge and restart itself even after the system suspend has finished. This could lead to unexpected system behavior or resource management problems.

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.
