RCE in Google Chrome V8 via crafted HTML page
CVE-2026-3910 is a high-severity inappropriate implementation vulnerability in the V8 JavaScript and WebAssembly engine in Google Chrome prior to 146.0.7680.75/.76. Public reporting states that a remote attacker can trigger the flaw by getting a target to load a crafted HTML page, leading to arbitrary code execution inside the Chrome renderer sandbox. Multiple cited reports describe the issue only at a high level as an implementation flaw in V8, and Google restricted technical details because exploitation was observed in the wild. One exploitability-assessment context in the provided content characterizes the underlying issue as write-barrier elision leading to a use-after-free, but that detail is not corroborated by an official vendor description in the supplied material.
