CVE-2026-68331

A flaw was found in the Linux kernel's dpaa2-eth component. When a network device connects and then disconnects, a reference to the MAC endpoint device is not properly released. This oversight causes a resource leak with each successful connection and subsequent disconnection. Repeated exploitati...
