Donenfeld <Jason@zx2c4.com> # Date: Thu Feb 6 12:42:01 2020 +0100 # # crypto: chacha20poly1305 - prevent integer overflow on large input # # This code assigns src_len (size_t) to sl (int), which causes problems # when src_len is very large. Probably nobody in the kernel should be # passing this much data to chacha20poly1305 all in one go anyway, so I # don't think we need to change the algorithm or introduce larger types # or anything. But we should at least error out early in this case and # print a warning so that we get reports if this does happen and can look # into why anybody is possibly passing it that much data or if they're # accidently passing -1 or similar. # # Fixes: d95312a3ccc0 ("crypto: lib/chacha20poly1305 - reimplement crypt_from_sg() routine") # Cc: Ard Biesheuvel <ardb@kernel.org> # Cc: stable@vger.kernel.org # 5.5+ # Signed-off-by: Jason A.
