Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A reference leak issue in the Linux kernel's ASoC rockchip component has been identified. The problem occurs because pm runtime get sync increments the PM usage counter even if it fails, and forgetting to put the operation will result in a reference leak. This issue is resolved by replacing pm runtime get sync with pm runtime resume and get to keep the usage counter balanced.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
