Description
A flaw was found in the Linux kernel's Industrial I/O (IIO) core, specifically within the gp2ap002 light sensor driver. A local attacker with appropriate permissions could exploit this by repeatedly writing the same value to the event enable attribute. This can lead to an unbalanced runtime Power Management (PM) state, causing a denial of service (DoS) by either preventing the device from suspending or triggering a usage count underflow warning.
