A flaw was found in the Linux kernel's bh1780 light sensor driver. This vulnerability occurs due to a Power Management (PM) runtime leak, where the system's reference count for power management is not always properly decremented. An attacker could exploit this by repeatedly triggering the error path, leading to resource exhaustion. This can result in a Denial of Service (DoS), making the system unresponsive or unstable.
