-Subject: [PATCH] virtio-crypto: fix possible integer and heap overflow
-
-Because the 'size_t' type is 4 bytes in 32-bit platform, which
-is the same with 'int'. It's easy to make 'max_len' to zero when
-integer overflow and then cause heap overflow if 'max_len' is zero.
-
-Using uint_64 instead of size_t to avoid the integer overflow.
