DescriptionCVE.org

Out of bounds read in WebGPU in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page. (Chromium security severity: Medium)

AnalysisAI

Out-of-bounds memory read in the WebGPU component of Google Chrome before 149.0.7827.53 allows a remote attacker to read memory outside intended buffer boundaries when a victim visits a crafted HTML page. The flaw carries a CVSS 8.1 score due to network reachability and high confidentiality/availability impact, but EPSS sits at 0.03% and SSVC reports no observed exploitation, so the practical risk is currently low despite the high CVSS. No public exploit identified at time of analysis.

Technical ContextAI

WebGPU is Chrome's modern GPU API (successor to WebGL) that exposes lower-level access to the host GPU for rendering and compute workloads via JavaScript running in the renderer process. The root cause is CWE-125 (Out-of-bounds Read), a memory safety class where the implementation reads past the end of an allocated buffer - typically due to missing bounds validation on attacker-influenced indices, sizes, or descriptors passed into the WebGPU command pipeline. Because WebGPU command buffers and shader inputs are derived from untrusted page content, malformed structures can steer reads beyond allocated GPU/CPU buffers in the renderer, potentially leaking adjacent memory contents. Affected CPE is cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* across desktop builds prior to the stable channel update.

RemediationAI

Vendor-released patch: update Google Chrome to 149.0.7827.53 or later on the Stable channel per the advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html. Restart the browser after update to ensure the patched renderer binary is loaded, and for managed fleets push the update via enterprise update channels (Chrome Browser Cloud Management, Group Policy, MDM) and verify chrome://version reflects the fixed build. Users of Chromium-derived browsers should apply the equivalent vendor release once it incorporates the upstream fix referenced in https://issues.chromium.org/issues/497183443. As a temporary compensating control until patched, WebGPU can be disabled by launching Chrome with --disable-features=WebGPU or via the chrome://flags 'Unsafe WebGPU Support' toggle / enterprise policy - trade-off is loss of WebGPU-accelerated rendering and compute for sites that depend on it (some games, ML demos, design tools).
