CVE-2026-89939

A flaw was found in the Linux kernel's iio: chemical: atlas-sensor driver. This vulnerability occurs when the atlas_buffer_postenable() function acquires a Power Management (PM) reference but fails to release it if an interrupt setup operation (atlas_set_interrupt()) does not complete successfully. This unreleased reference prevents the affected device from entering an autosuspend state, potentially leading to resource exhaustion or a denial of service.
