Missing Release of Resource after Effective Lifetime in Linux kernel - CVE-2026-98191

Vulnerability details

The vulnerability allows a local user to cause a runtime power-management reference leak.

The vulnerability exists due to failure to release a runtime power-management reference in wlcore_regdomain_config() when handling a failed regulatory-domain command. A local user can trigger a regulatory-domain command failure to cause a runtime power-management reference leak.

The recovery worker acquires a separate runtime power-management reference and cannot release the reference held by this function.
