Arbitrary Code Execution in Chrome V8 via Crafted HTML Page
CVE-2026-3910 is a high-severity inappropriate implementation vulnerability in the V8 JavaScript/WebAssembly engine in Google Chrome. According to the provided content, affected versions are Chrome prior to 146.0.7680.75/.76, and successful exploitation allows a remote attacker to execute arbitrary code inside the browser sandbox by inducing the target to load a crafted HTML page. Public reporting in the supplied material consistently describes the issue only at a high level as an implementation flaw in V8; no authoritative vulnerable function, root-cause commit, or precise memory-corruption primitive is provided in the source material. One mention in the supplied context claims the issue involved write-barrier elision leading to use-after-free, but that detail is not corroborated by an official advisory in the provided content, so the exact low-level bug mechanism remains currently not available from the supplied sources.
