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

Description: A crash can occur when enabling runtime PM for clock suppliers that also belong to a power domain. This is due to the power domain being cut off after clk register() is called, leading to a synchronous external abort error when attempting to access the BLK CTL register. The issue arises from using pm runtime enable() instead of devm pm runtime enable(), along with unnecessary pm runtime disable() in the cleanup path.

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