CVE-2024-7971 is a high-severity type confusion vulnerability in the Chromium V8 JavaScript and WebAssembly engine affecting Google Chrome and other Chromium-based browsers prior to 128.0.6613.84. By causing incorrect type handling in V8, a remote attacker can trigger heap corruption through specially crafted HTML content. In observed attacks, exploitation was used to achieve remote code execution within the sandboxed Chromium renderer process. The vulnerability was reported as actively exploited in the wild in August 2024.
