AI-suggested
A patch is available and has been released in Linux kernel versions 7.0.0-31.31 and later for the linux-hwe-edge and related packages. Users should update their systems to these fixed versions to resolve the runtime PM leak. After updating, a system reboot is required to apply the kernel changes. Additionally, due to an ABI change, third-party kernel modules must be recompiled and reinstalled. Follow the vendor's update instructions carefully.
Description
In the Linux kernel, the following vulnerability has been resolved: iio: pressure: mpl115: fix runtime PM leak on read error mpl115_read_raw() takes a runtime PM reference with pm_runtime_get_sync() before reading the processed pressure or raw temperature, but on the read error path it returns without calling pm_runtime_put_autosuspend(). Each failed read therefore leaks a runtime PM reference and prevents the device from autosuspending. Drop the reference before checking the return value so both the success and error paths are balanced.
