Doc Text:	A flaw was found in the Linux kernel's `apds9306` light sensor driver. This issue occurs because certain error paths within the `apds9306_read_data()` function fail to properly release a power management reference. This oversight leads to a resource leak, which can prevent the affected device from entering a low-power autosuspend state. Consequently, the device may consume more power than necessary, potentially impacting system battery life or overall energy efficiency.	Story Points:	---

Description OSIDB Bzimport 2026-09-16 11:40:37 UTC

In the Linux kernel, the following vulnerability has been resolved:

iio: light: apds9306: fix PM reference leak in apds9306_read_data()

apds9306_read_data() calls pm_runtime_resume_and_get() but several
error paths return directly without calling pm_runtime_put_autosuspend(),
leaking the runtime PM reference and preventing the device from
autosuspending.

Use PM_RUNTIME_ACQUIRE_AUTOSUSPEND() and PM_RUNTIME_ACQUIRE_ERR() to
automatically handle runtime PM reference release on all return paths.
