What to do
AI-suggested
A fix is available that corrects the error handling in kxsd9_write_raw() to properly release the runtime PM reference. Users should apply the updated Linux kernel version containing this fix once it is released.
Description
A vulnerability in the Linux kernel's kxsd9 accelerometer driver caused a runtime power management (PM) reference leak when write_raw() returned an error. This leak prevents the device from autosuspending properly, potentially impacting power management.
