CVE-2026-82344Network attack vector

Unauthenticated code execution via TDS reassembly overflow

Published Oct 8, 2026 · Updated Oct 8, 2026

Heap overflow in IBM Guardium Data Protection 12.0 and 12.1 allows remote attackers to execute code via crafted TDS login fragments. The supplied source record describes S-TAP TrafficTap assembling fragments beyond a fixed-size heap buffer before authentication, with code execution or denial of service as the reported consequences. Retrieved IBM material does not independently corroborate this CVE, establish the denial-of-service failure mode, or resolve the catalog's additional 12.2 applicability claim.
