Miggo AIRoot Cause Analysis

  1. The vulnerability description explicitly names OPENSSL_LH_flush as the problematic function.
  2. The commit diff shows the fix adds 'lh->num_items = 0' to this function, confirming improper cleanup.
  3. CWE-459 (Incomplete Cleanup) directly maps to the failure to reset the item count.
  4. All advisory sources (OpenSSL, NVD, RustSec) consistently reference this function as the root cause.
  5. The memory leak mechanism described matches the function's responsibility for hash table management during certificate/key decoding operations.
