# CVE-2026-102725: Out-of-bounds Read from Unvalidated MSRP Attribute List Length

Status: published. Published: 2026-09-29. Updated: 2026-11-04.

In Eclipse ThreadX NetX Duo versions 6.4.0 through 6.5.2.202603a, built with VLAN and SRP support, the MSRP parser uses the attribute list length from the received frame without comparing it with the packet length. An unauthenticated station on the same Layer 2 segment can send a short MSRP frame declaring a long list and make the MRP worker read far past the received packet, faulting it on targets with memory protection.
