AI-suggested

A patch is available and has been released in multiple Linux kernel versions including 6.8.0-147.147 and later. Users and administrators should update to these fixed kernel versions to resolve the runtime PM leak issue. No additional mitigation steps are required beyond applying the official fix.

Description

A vulnerability in the Linux kernel's mpl115 pressure sensor driver caused a runtime power management (PM) reference leak on read errors. The function mpl115_read_raw() took a runtime PM reference but failed to release it on error, preventing the device from autosuspending properly. This flaw has been fixed by balancing the PM reference release on both success and error paths.
