Out-of-bounds reads based on pointer access.

PTAL :)

I've tested asan with two patches.
how could I commit those two patches at the same time?
AFAIK, asan bot is running. is it part of build bot?

You can't land them at the same time.  You should land this one first.  Once
it's been in the tree for a few hours, you can land the Blink side.
