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 exploitation of this flaw could lead to resource exhaustion, potentially resulting in a Denial of Service (DoS) for the system.

This issue affects NXP DPAA2 Ethernet interfaces. On MAC disconnect, the endpoint device reference from fsl_mc_get_endpoint() is not released, leaking device references. Systems without DPAA2 Ethernet hardware are not affected.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

To mitigate this issue, prevent the fsl_dpaa2_eth module from loading. See https://access.redhat.com/solutions/41278 for instructions.
