Integer overflow in DevTools in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Remote code execution in Google Chrome versions prior to 149.0.7827.53 allows a remote attacker to execute arbitrary code inside the renderer sandbox by enticing a victim to visit a crafted HTML page that triggers an integer overflow in DevTools. Google has rated this Chromium issue as High severity and a vendor patch is available; no public exploit identified at time of analysis, and the bug is not currently listed in CISA KEV.

Technical ContextAI

The flaw resides in Chrome's DevTools subsystem and is classified as CWE-472 (External Control of Assumed-Immutable Web Parameter), manifesting as an integer overflow when handling values supplied via a crafted HTML page. Integer overflows in DevTools typically arise when untrusted size or index values from page content are used in arithmetic without bounds checking, producing wrapped values that subsequently corrupt memory operations in the renderer. Because exploitation occurs inside Chrome's sandbox, a successful exploit gains code execution in the renderer process but would still require a separate sandbox escape to achieve full host compromise - a common pairing in Chrome exploit chains. Affected CPE coverage centers on Google Chrome desktop builds below 149.0.7827.53 across supported platforms.

RemediationAI

Vendor-released patch: upgrade Google Chrome to 149.0.7827.53 or later on all desktop platforms per the Chrome stable channel advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop.html, and force-restart browsers to ensure the new binary is loaded. Track downstream Chromium-based browsers (Microsoft Edge, Brave, Opera, Vivaldi) and Electron applications for corresponding security releases and update them as soon as patched builds are published. As a compensating control until patching completes, administrators can use enterprise policy to disable DevTools (DeveloperToolsAvailability = DeveloperToolsDisallowed) on managed endpoints, which removes the vulnerable surface but breaks legitimate developer workflows; additionally, browser isolation or strict site-blocking of untrusted destinations reduces exposure to attacker-controlled HTML at the cost of usability. Further context is available via the Chromium issue tracker entry https://issues.chromium.org/issues/511290038 (likely access-restricted until the disclosure window closes) and the NVD record https://nvd.nist.gov/vuln/detail/CVE-2026-10965.
