struct sha256_ctx_mgr allocated in sha256_mb_mod_init() via kzalloc() and later passed in sha256_mb_flusher_mgr_flush_avx2() function where instructions vmovdqa used to access the struct. vmovdqa requires 16-bytes aligned argument, but nothing guarantees that struct sha256_ctx_mgr will have that alignment. Unaligned vmovdqa will generate GP fault. Fix this by replacing vmovdqa with vmovdqu which doesn't have alignment requirements. Fixes: a377c6b1 ("crypto: sha256-mb - submit/flush routines for AVX2") Reported-by:
