CVE-2022-49128

5.5 MEDIUM
Published: February 26, 2025 Modified: October 01, 2025

Description

In the Linux kernel, the following vulnerability has been resolved: drm/bridge: Add missing pm_runtime_put_sync pm_runtime_get_sync() will increase the rumtime PM counter even when it returns an error. Thus a pairing decrement is needed to prevent refcount leak. Fix this by replacing this API with pm_runtime_resume_and_get(), which will not change the runtime PM counter on error. Besides, a matching decrement is needed on the error handling path to keep the counter balanced.
