Overview
CVE-2026-98191 is a known-severity vulnerability. It was published on October 6, 2026.
Technical 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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
