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

Description A flaw exists in the Linux kernel’s DRM/Rockchip LVDS subsystem related to power management usage counters. The pm runtime get sync function increments the power management usage counter even when it fails, leading to a reference leak if the corresponding put operation is omitted. This issue is addressed by replacing the function with pm runtime resume and get to maintain a balanced usage counter.

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