overwrites unallocated memory in the following memset() because I used the
wrong buffer length.

Good catch.  Thanks!

We don't have any in-tree users that will trigger this right
now do we?

Why not? This is used by _any_ cipher/hash/... user in tree. Most of
algos specify an alignment of 3 what is very likely to become. I
checked IPsec and they allocated keys with an alignment of 7.
padlock-aes specifies an alignment of 15 so there is a 50-50 chance that
it will go well :)
I don't know if you count this as user, but tcrypt.c has an alignment of
3 and the tgr hash needs 7.

Cheers,
