Out of bounds read and write in V8 in Google Chrome prior to 148.0.7778.96 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Out-of-bounds memory access in Chrome's V8 JavaScript engine enables remote code execution within the browser sandbox when users visit malicious websites. Affects all Chrome versions prior to 148.0.7778.96 across Windows, macOS, and Linux. Google released patches in the stable channel update (build 148.0.7778.96) per May 2026 advisory. No active exploitation confirmed at time of analysis, but CVSS 8.8 indicates high severity and the vulnerability requires only user interaction (visiting a crafted webpage) with no authentication needed.
Technical ContextAI
This vulnerability resides in V8, Google's open-source JavaScript and WebAssembly engine that powers Chrome and Chromium-based browsers. The flaw is classified as CWE-125 (Out-of-bounds Read) but also involves out-of-bounds write capability according to the description, enabling both information disclosure and memory corruption. V8 performs just-in-time (JIT) compilation of JavaScript, and memory safety bugs in this component can allow attackers to escape normal JavaScript security boundaries. The CPE string cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:* confirms this affects the Chrome application suite. While exploitation occurs within Chrome's sandbox (a defense-in-depth layer that isolates renderer processes), arbitrary code execution in the sandbox is the first stage of browser exploitation chains and can be combined with sandbox escape vulnerabilities.
RemediationAI
Update Google Chrome to version 148.0.7778.96 or later via the stable channel release published May 2026. Chrome's auto-update mechanism deploys patches automatically for most users within 24-48 hours; administrators can verify versions at chrome://settings/help and force immediate update checks. Enterprise deployments using managed Chrome policies should prioritize distribution of build 148.0.7778.96 through update channels (reference: chromereleases.googleblog.com/2026/05/stable-channel-update-for-desktop.html). For environments unable to immediately patch, implement compensating controls: disable JavaScript execution for untrusted sites via Chrome's site settings (reduces functionality significantly for modern web applications), deploy Enhanced Safe Browsing mode to block known malicious sites, and utilize network-level filtering to restrict browser access to only approved domains (creates substantial operational overhead for general-purpose browsing). Chromium-based browser users should monitor their respective vendor advisories (Microsoft Edge Security Updates, Brave release notes) for equivalent patches incorporating the V8 fix.
