crypto: authenc - don't leak pointers to authenc keys
[ Upstream commit ad2fdcdf75d169e7a5aec6c7cb421c0bec8ec711 ]
In crypto_authenc_setkey we save pointers to the authenc keys in
a local variable of type struct crypto_authenc_keys and we don't
zeroize it after use. Fix this and don't leak pointers to the
authenc keys.
