CVE-2026-45926
Description
A flaw was found in the Linux kernel. When initializing a Pulse Width Modulation (PWM) chip, a memory leak can occur if the pwmchip_alloc() function fails. This happens because the allocated pwm_chip's initial reference is not properly released, leading to unmanaged memory consumption. This vulnerability could potentially impact system stability and resource availability.
