Thanks to the crbug url we can find the bug regression test.
After analysing poc we deduce we can have two Arrays with JS Elements to the same addr (size > 0) which is an amazing property.
So we can leak and prepare a fake ArrayBuffer.
the next steps:
1. leaking a function add.
2. leaking JIT addr.
3. Writing shellcode.
4. Pwn!
