Descriptions

Out of bounds memory access in Mojo in Google Chrome prior to 114.0.5735.90 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

During a Mojo IPC method call, there are multiple stages of validation and deserialization that take place. These assume that the contents of the message cannot be modified during the deserialization process, but the new core_ipcz implementation returns message contents directly in shared memory.
