Use after free in Dawn in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Memory-corruption remote code execution in Google Chrome's Dawn WebGPU graphics component affects all Desktop builds prior to 151.0.7922.72, where a crafted HTML page triggers a use-after-free (CWE-416) that lets a remote attacker run arbitrary code - though confined inside the renderer sandbox, which is why Chromium rated it Low despite the CVSS 8.8. Exploitation requires only that a victim load a malicious page (UI:R), with no authentication. There is no public exploit identified at time of analysis and the CVE is not on CISA KEV.

Technical ContextAI

Dawn is Chromium's cross-platform implementation of the WebGPU API, the successor to WebGL that gives web pages low-level access to GPU compute and rendering. It parses and validates GPU commands originating from untrusted JavaScript, making it a rich attack surface for memory-safety bugs. The flaw is a use-after-free (CWE-416): an object is freed while a dangling reference remains reachable, and subsequent access to that stale pointer allows an attacker to corrupt heap memory and hijack control flow. The single affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*, i.e. the Chrome desktop application; because Dawn is also embedded in other Chromium-based browsers (Edge, Brave, Opera, Electron apps), downstream products built on the same engine may share the underlying defect.

RemediationAI

Vendor-released patch: update Google Chrome to 151.0.7922.72 or later via the Stable Desktop channel (chrome://settings/help forces the update check, then relaunch to apply). Enterprise fleets should push the update through their managed-browser channel and confirm relaunch, since Chrome's background updater does not take effect until restart. Reference advisory: https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. If immediate patching is not possible, reduce exposure by disabling WebGPU via enterprise policy or the chrome://flags/#enable-unsafe-webgpu toggle, which removes the Dawn attack surface at the cost of breaking GPU-accelerated web applications; avoiding untrusted sites and maintaining standard sandbox hardening further limit risk. Users of other Chromium-based browsers should apply their vendor's corresponding Dawn update when released.
