CVE-2026-43181

A flaw was found in the Linux kernel's GPIO (General Purpose Input/Output) and sysfs subsystems. When a GPIO is exported through sysfs and its parent controller is removed, the system fails to properly unexport the GPIO attribute. This oversight prevents the final reference to the GPIO descriptor from being dropped, leading to a resource leak. Repeated exploitation of this flaw could result in resource exhaustion, potentially causing a Denial of Service (DoS) condition.
