CVE-2026-89939

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.
