AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Network-reachable via a web page with only user interaction (UI:R) and no privileges; the use-after-free enables a sandbox escape, so scope changes (S:C) with high C/I/A impact.

Use after free in Dawn in Google Chrome prior to 150.0.7871.46 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Critical)
AnalysisAI
Sandbox escape in Google Chrome's Dawn (WebGPU) component affects all desktop builds prior to 150.0.7871.46, where a use-after-free lets a remote attacker who lures a victim to a crafted HTML page potentially break out of the renderer sandbox. Google rates the Chromium severity Critical, and the CVSS 3.1 score of 9.6 reflects a scope-changing memory-corruption bug. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, though a vendor patch is already shipping in the Stable channel.
Technical ContextAI
Dawn is Chromium's cross-platform implementation of the WebGPU API, which exposes GPU compute and rendering to web content through JavaScript. Because Dawn processes attacker-influenced GPU command buffers and object lifetimes on behalf of untrusted web pages, memory-safety errors in it are especially dangerous. This issue is CWE-416 (Use After Free): an object is freed while a reference to it is still used, letting an attacker reclaim and control the freed memory to corrupt state. Given the S:C (scope change) in the CVSS vector, exploitation targets the boundary between the sandboxed renderer and higher-privileged browser/GPU process, i.e. a sandbox escape rather than a simple renderer crash. The affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* across desktop platforms.
RemediationAI
Vendor-released patch: update to Google Chrome 150.0.7871.46 or later on Windows, macOS, and Linux; the fix is delivered through the Stable channel and takes effect on browser restart, so ensure Chrome is fully relaunched to complete the update. See the Chrome release advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. Where immediate patching is not possible, the practical compensating control is to disable the WebGPU attack surface via chrome://flags/#enable-unsafe-webgpu and related WebGPU flags or enterprise policies, which prevents Dawn from processing untrusted GPU workloads at the cost of breaking legitimate WebGPU sites and GPU-accelerated web applications. Enterprise fleets should push the updated version through managed update policies rather than relying on user-initiated restarts.
