The original assembly imported from OpenSSL has two copy-paste errors in handling CTR mode. When dealing with a 2 or 3 block tail, the code branches to the CBC decryption exit path, rather than to the CTR exit path. This leads to corruption of the IV, which leads to subsequent blocks being corrupted. This can be detected with libkcapi test suite, which is available at https://github.com/smuellerDD/libkcapiReported-by:
