Until a fix is available, network administrators should consider limiting access to the Layer 2 segment to trusted devices and monitor for unusual attribute declarations that could trigger this condition.
Description
CVE-2026-102723 is a high-severity vulnerability in Eclipse ThreadX NetX Duo versions 6.4.0 through 6.5.2.202603a when built with VLAN and SRP support. It involves a NULL pointer dereference caused by the MSRP attribute lookup writing through a null pointer when the attribute table is full. An unauthenticated attacker on the same Layer 2 segment can trigger this fault by declaring enough new attributes, leading to a fault in the MRP worker thread. Talker Failed declarations exacerbate the issue by holding table entries indefinitely.
