A heap buffer overflow in GPU in Google Chrome prior to 70.0.3538.67 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
