AI-suggested
A patch is available and should be applied to affected Linux kernel versions to resolve the runtime PM leak. The fix ensures proper release of the runtime PM reference on error paths. Users should update to the fixed kernel versions as provided by their Linux distribution vendor.
Description
A vulnerability in the Linux kernel's gp2ap002 light sensor driver caused a runtime power management (PM) reference leak on read errors. The issue occurs because the function gp2ap002_read_raw() calls pm_runtime_get_sync() but returns early on failure without releasing the PM reference, preventing the device from autosuspending. This flaw has been fixed by ensuring the PM reference is properly released on error paths.
