CVE-2026-89939

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A power management (PM) reference leak occurs in the atlas buffer postenable() function. The function acquires a runtime PM reference using pm runtime resume and get(), but if the subsequent atlas set interrupt() function fails, the reference is not released. This leak prevents the device from entering the autosuspend state, which is a power-saving mode where the system automatically puts an idle device to sleep.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
