## Description

In the Linux kernel, the following vulnerability has been resolved:  crypto: keembay - Fix AEAD unregister count in error path  register_aes_algs() registers the AEAD algorithms before registering the skcipher algorithms.  If skcipher registration fails, the function unwinds the earlier AEAD registration with crypto_engine_unregister_aeads(), but it passes ARRAY_SIZE(algs), which is the skcipher table size.  Use ARRAY_SIZE(algs_aead) for the AEAD unwind path so the unregister helper iterates over the same table that was registered.  Also clarify the nearby comment: the crypto registration helpers clean up algorithms registered within the same call, while this function must still unwind earlier successful registration steps.
