The LLM security debt is doubly permanent along independent dimensions: informationally unpatchable (capability and vulnerability are the same compressed information — removing memorized data degrades capability) AND distributionally irretirable (weights already released cannot be recalled and embed the vulnerability permanently), making the training-data security surface not merely difficult but impossible to remediate through any known mechanism.

Justifications

SL — Information-theoretic inseparability (from Chinchilla's compression foundation) and distribution irreversibility (from weight diffusion) are independent permanence mechanisms — either alone prevents remediation, together they foreclose it completely

Antecedents (all must be IN):

  • IN capability-vulnerability-inseparability-makes-security-unpatchable — The training data security surface is not merely permanently permeable after weight release but fundamentally unpatchable: since language model quality directly measures compression capability and memorization is informationally inseparable from that compression, removing memorized vulnerabilities necessarily degrades the model's core competence — the vulnerability IS the capability.
  • IN security-debt-irretirable-after-weight-release — The security debt independently generated by both technical advances and market dynamics becomes significantly harder to retire once model weights are released: weight diffusion makes the training-data security surface fundamentally uncontainable after release, meaning that accumulated security debt from memorized training data and poisoned inputs propagates irreversibly through the ecosystem, though other security surfaces (such as prompt injection) may remain partially addressable through post-release mitigations.
