CVE-2025-71227

Description

A flaw was found in the Linux kernel's mac80211 WiFi subsystem. When a regulatory change disables a channel between the time it is scanned and when a connection attempt is made, a kernel warning (WARN) is triggered. This fix replaces the warning with a more informative error message, as the warning was not appropriate for this recoverable condition.

Statement

This is a code quality fix that replaces an inappropriate WARN_ON with an error message. The warning could be triggered by legitimate regulatory domain changes during WiFi operations. No actual crash or security-relevant behavior occurs; the connection simply fails gracefully.

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.
