          "details": "This flaw is confined to gpgsm’s CMS AES‑GCM parsing and is not in a network‑listening service; exploitation requires the target to intentionally process a crafted CMS/S/MIME object and results only in accepting a non‑standard 4‑byte GCM authentication tag, with no code execution, privilege escalation, or availability impact. Practically, it is a probabilistic integrity bypass that depends on attacker control of the victim’s input stream rather than enabling remote compromise. Moreover, the affected CMS‑GCM decrypt path exists only in newer 2.4/2.5 branches; deployments using the older 2.2.x line lack this code path, further constraining exposure.",
