HIGH 8.8

DescriptionCVE.org

Inappropriate implementation in V8 in Google Chrome prior to 146.0.7680.75 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Chrome's V8 JavaScript engine contains an inappropriate implementation (CVE-2026-3910, CVSS 8.8) that allows remote attackers to execute arbitrary code within the browser sandbox via crafted HTML pages. KEV-listed with public PoC, this V8 vulnerability affects all Chromium-based browsers and enables drive-by exploitation through any web page containing malicious JavaScript.

Technical ContextAI

V8 is Chrome's high-performance JavaScript and WebAssembly engine. The implementation flaw creates a condition where V8's JIT compiler or runtime mishandles specific JavaScript constructs, leading to memory corruption. V8 vulnerabilities are particularly valuable because JavaScript execution is the most common attack surface in browsers — every webpage runs JavaScript, and V8 processes it all.

RemediationAI

Update Chrome to 146.0.7680.75+ immediately. Update all Chromium-based browsers. Consider disabling JIT compilation via --js-flags=--jitless for high-security environments (performance trade-off).
