CVE-2026-64503

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

Description An issue exists in the kxsd9 write raw() function where a runtime Power Management (PM) reference is acquired using pm runtime get sync() but is not released when a scale with a non-zero integer part is requested. In this scenario, the function returns -EINVAL immediately, skipping the pm runtime put autosuspend() call. This results in a leak of the runtime PM usage-counter reference, which prevents the device from entering the autosuspend state.

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