Eric Biggers d42d342022 crypto: arm64/aes-neonbs - don't access already-freed walk.iv ... commit 4a8108b705 upstream. If the user-provided IV needs to be aligned to the algorithm's alignmask, then skcipher_walk_virt() copies the IV into a new aligned buffer walk.iv. But skcipher_walk_virt() can fail afterwards, and then if the caller unconditionally accesses walk.iv, it's a use-after-free. xts-aes-neonbs doesn't set an alignmask, so currently it isn't affected by this despite unconditionally accessing walk.iv. However this is more subtle than desired, and unconditionally accessing walk.iv has caused a real problem in other algorithms. Thus, update xts-aes-neonbs to start checking the return value of skcipher_walk_virt().
