Miggo AIRoot Cause Analysis

The vulnerability stems from Java 13+ GC behavior causing premature key zeroing. Analysis focused on:

  1. Key destruction methods (destroy()) that clear sensitive data
  2. Finalizers in key classes that trigger cleanup
  3. Cryptographic operation initialization methods handling temporary keys While no direct patch code is shown, these functions align with the described use-after-free pattern in FIPS modules. The medium confidence reflects educated inference based on Bouncy Castle's architecture and Java GC interactions.
