CVE-2024-0519: The CVE That Got Away

An in-the-wild Chrome renderer 0-day patched January 2024 — no public root cause analysis for two years. This RCA traces it to a TOCTOU race in V8's JIT constant-folding pipeline → type confusion (`PropertyConstness::kConst` invariant violation) → OOB read/write. Invisible to JavaScript probes; only reproduces with a C++ harness.

Severity Inflation as a Signaling Failure: A Researcher's Quality Gate

AI scales the cost of producing a vulnerability report toward zero faster than it scales the cost of producing a correctly-scoped one. Spence's signaling cost asymmetry collapses as a result. This post documents the inflation antipatterns, the six-check quality gate, and the AI-side adversarial enforcement structure one researcher built in response.
