Summary

In Eclipse ThreadX NetX Duo versions 6.4.0 through 6.5.2.202603a, built with VLAN and SRP support, evicting the last attribute in an MRP participant's list writes through a null successor pointer. An unauthenticated station on the same Layer 2 segment can fault the MRP worker thread by declaring one MSRP attribute and withdrawing it, and ordinary withdrawals by legitimate stations reach the same path.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
