Vulnerability from github – Published: 2026-10-06 09:31 – Updated: 2026-10-06 09:31

Details

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
