CVE-2026-90215

A flaw was found in the Linux kernel's Unsorted Block Images UBI subsystem. When a UBI device is busy and ubidetachmtddev is called, a device reference is not properly released. This oversight prevents the device object from being freed later, potentially leading to a resource leak. An attacker...
