CVE-2026-89934

A flaw was found in the Linux kernel's ltrf216a driver, which manages light sensors. When the system attempts to read data from the sensor, a power management (PM) reference is acquired. If the data reading operation fails, this reference is not properly released. This oversight leads to an unbalanced power management usage count, preventing the affected device from automatically suspending and resulting in a denial of service for power management features.
