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.
