Technical details

A use-after-free (UAF) vulnerability exists in Dawn, the WebGPU implementation in Chromium. The flaw (CWE-416) can be triggered by a remote attacker via a crafted HTML page. Exploitation requires the attacker to have already compromised the renderer process (a 'sandbox escape' or 'chain' scenario). Successful exploitation allows for arbitrary code execution in the context of the browser. Google has confirmed that this vulnerability is being exploited in the wild. The issue is resolved in Chrome version 146.0.7680.178 and later.
