Which versions of Google Chrome are affected by EUVD-2026-50616?

Google Chrome desktop environments face a critical vulnerability (CVE-2026-17867) that could enable attackers to break out of the browser sandbox and gain system-level access when users visit…. A patch is available.

How to fix or mitigate EUVD-2026-50616?

Within 24 hours, conduct a Chrome version audit across all managed desktop endpoints to identify systems running versions prior to 151.0.7922.72 and assess user populations most exposed to untrusted web content. Within 7 days, initiate staged deployment of Chrome 151.0.7922.72 or later through your endpoint management platform, beginning with non-production systems and test groups to validate application compatibility before organization-wide rollout. Within 30 days, complete mandatory updates to Chrome 151.0.7922.72 or later across all desktop instances, with verification through endpoint telemetry and documented sign-off for any systems unable to patch.

DescriptionCVE.org

Insufficient validation of untrusted input in Dawn in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Sandbox escape in Google Chrome's Dawn (WebGPU) component affects all desktop Chrome builds prior to 151.0.7922.72, where insufficient validation of untrusted input lets a remote attacker who lures a victim to a crafted HTML page potentially break out of the renderer sandbox. Chromium rates the severity Medium and the issue carries a CVSS 7.1 with scope change, but there is no public exploit identified at time of analysis and EPSS is very low at 0.18% (8th percentile). Google has shipped a patched Stable channel release addressing it.

Technical ContextAI

Dawn is Chromium's open-source implementation of the WebGPU API, providing web pages low-level access to the GPU for compute and rendering. Because WebGPU exposes a large, complex native surface (command validation, resource binding, shader inputs) to untrusted JavaScript running in the sandboxed renderer, flaws here are a recurring sandbox-escape vector. The root cause is classified as CWE-20 (Improper Input Validation): Dawn does not sufficiently validate untrusted parameters supplied by web content, which can be leveraged to cross the renderer/host trust boundary - reflected in the CVSS scope change (S:C). The affected component matches CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*.

RemediationAI

Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on all desktop platforms; Chrome's automatic updater will normally apply this, so verify via chrome://settings/help and relaunch to complete installation, and in managed fleets push the update through your management channel and confirm rollout. Reference the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. If immediate patching is not possible, the exploitation prerequisite of WebGPU means a compensating control is to disable WebGPU/Dawn by launching Chrome with --disable-features=WebGPU or via the corresponding enterprise policy, which blocks the affected code path at the cost of breaking legitimate WebGPU-based sites and applications; user-awareness measures to avoid untrusted links reduce but do not eliminate exposure since only a page visit is required.
