Integer overflow in Mojo in Google Chrome prior to 90.0.4430.85 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
