CVE-2026-98191

CVE Details

Release Date:	2026-10-06
Impact:	Moderate	What is this?

Description

In the Linux kernel, the following vulnerability has been resolved: wifi: wlcore: release runtime PM ref on regdomain config failure wlcore_regdomain_config() gets a runtime PM reference before sending the regulatory-domain command. When wlcore_cmd_regdomain_config_locked() fails, the function queues recovery and returns without dropping that reference. Release the reference after handling the command result so both success and failure paths balance the preceding pm_runtime_resume_and_get(). The recovery worker takes a separate runtime PM reference and cannot release the reference held here.
