Can you explain this vulnerability to me?
This vulnerability exists in the Linux kernel within the regulator component fp9931, specifically in the function fp9931_hwmon_read(). If the regmap_read() call fails, the function returns an error code without calling pm_runtime_put_autosuspend(), which leads to a power management (PM) runtime reference leak.
How can this vulnerability impact me? :
The impact of this vulnerability is a leak of PM runtime references, which can cause improper power management behavior. Over time, this may lead to increased power consumption or resource exhaustion related to power management, potentially affecting system stability or battery life.
