Out of bounds read in Dawn in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: Low)

AnalysisAI

Out-of-bounds memory read in the Dawn (WebGPU) component of Google Chrome before 151.0.7922.72 lets a remote attacker read memory outside intended bounds when a victim opens a crafted HTML page. Google's Chrome team reported it and a fixed Stable-channel build is available; there is no public exploit identified at time of analysis and EPSS exploitation probability is low (0.17%, 7th percentile). Notably, Chromium internally rated the security severity 'Low' even though the NVD-style CVSS base score is 8.1, so real-world impact is likely narrower than the raw score implies.

Technical ContextAI

Dawn is Chromium's cross-platform implementation of the WebGPU API, translating web-facing GPU calls into native Metal/Vulkan/D3D12/OpenGL commands; it runs largely within the renderer/GPU process and parses untrusted, web-supplied graphics workloads. The flaw is CWE-125 (Out-of-bounds Read), meaning code reads past the end (or before the start) of an allocated buffer - typically from missing or incorrect bounds validation on an index, length, or offset derived from attacker-controlled WebGPU input. The single affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*, and it is triggered purely through content rendered from a crafted HTML page that exercises the WebGPU/Dawn code path.

RemediationAI

Vendor-released patch: update Google Chrome to 151.0.7922.72 or later on the Stable channel; Chrome normally auto-updates, so the primary action is to relaunch the browser to apply the pending update and confirm the version under chrome://settings/help across managed fleets. Follow the vendor advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html and the issue tracker at https://issues.chromium.org/issues/520972775. If patching must be delayed, a specific compensating control is to disable WebGPU (set chrome://flags/#enable-unsafe-webgpu to Disabled, or enforce via enterprise policy) so the vulnerable Dawn code path is not reachable from web content; the trade-off is that any legitimate WebGPU-based sites or apps will lose GPU acceleration/functionality. Restricting exposure to untrusted pages (site isolation is already on by default) further limits opportunity but is not a substitute for the update.
