CVE-2026-64022
Description
A flaw was found in the Linux kernel's GPIO (General Purpose Input/Output) aggregator component. When the aggregator device is deactivated after being configured using configfs, a dynamic software node is not properly removed. This oversight leads to a resource leak, which could potentially be exploited by a local attacker to cause a Denial of Service (DoS) by exhausting system resources.
