A stale\n  next_buffer pointer can lead to a use-after-free on subsequent\n  error paths.\n- Update pdu_length to the decrypted plaintext size (buf_size). Using\n  the pre-decryption length allows NextCommand to point into stale\n  ciphertext residue.\n- Reject next_cmd values smaller than MID_HEADER_SIZE(server).\n- Fix an integer overflow in the upper bound check by verifying\n  pdu_length - next_cmd < MID_HEADER_SIZE(server), ensuring the\n  trailing slice is large enough for a header.",
