iio: chemical: atlas-sensor: fix PM reference leak in buffer postenable

State: Published
Severity: Not scored
Published: Sep 16, 2026
Updated: Oct 19, 2026
Reserved: Sep 11, 2026

Description

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

iio: chemical: atlas-sensor: fix PM reference leak in buffer postenable

atlas_buffer_postenable() acquires a runtime PM reference with pm_runtime_resume_and_get() but returns the result of atlas_set_interrupt() directly. If atlas_set_interrupt() fails, the runtime PM reference is leaked and the device can never autosuspend.

Add pm_runtime_put_autosuspend() on the error path to balance the reference.
