CVE-2026-64503

A flaw was found in the Linux kernel's iio subsystem, specifically in the kxsd9 accelerometer driver. A local user could exploit this by requesting a scale with a non-zero integer part through the kxsd9_write_raw() function. This action causes a runtime Power Management (PM) usage-counter reference to leak, preventing the device from entering autosuspend mode. The consequence is increased power consumption and a denial of service for the device's power management capabilities.
