CVE-2026-102723

EUVD-2026-89189
In Eclipse ThreadX NetX Duo versions 6.4.0 through 6.5.2.202603a, built with VLAN and SRP support, the MSRP attribute lookup writes through the null pointer returned by its allocator when the ten-entry attribute table is full. An unauthenticated station on the same Layer 2 segment can fault the MRP worker thread by declaring enough new attributes, and Talker Failed declarations hold table entries that are never released.
