V8 Engine | Breaking Cybersecurity News | The Hacker News

Google has released security updates to address a vulnerability in its Chrome browser for which an exploit exists in the wild. The zero-day vulnerability, tracked as CVE-2025-6554 (CVSS score: N/A), has been described as a type confusing flaw in the V8 JavaScript and WebAssembly engine. "Type confusion in V8 in Google Chrome prior to 138.0.7204.96 allowed a remote attacker to perform arbitrary read/write via a crafted HTML page," according to a description of the bug on the NIST's National Vulnerability Database (NVD). Type confusion vulnerabilities can have severe consequences as they can be exploited to trigger unexpected software behavior, resulting in the execution of arbitrary code and program crashes. Zero-day bugs like this are especially risky because attackers often start using them before a fix is available. In real-world attacks, these flaws can let hackers install spyware, launch drive-by downloads, or quietly run harmful code — sometimes just by getting...

Google has rolled out security fixes to address a high-severity security flaw in its Chrome browser that it said has come under active exploitation in the wild. Tracked as CVE-2024-7971 , the vulnerability has been described as a type confusion bug in the V8 JavaScript and WebAssembly engine. "Type confusion in V8 in Google Chrome prior to 128.0.6613.84 allowed a remote attacker to exploit heap corruption via a crafted HTML page," according to a description of the bug in the NIST National Vulnerability Database (NVD). The Microsoft Threat Intelligence Center (MSTIC) and Microsoft Security Response Center (MSRC) have been credited with discovering and reporting the flaw on August 19, 2024. No additional details about the nature of the attacks exploiting the flaw or the identity of the threat actors that may be weaponizing it have been released, primarily to ensure that a majority of the users are updated with a fix. The tech giant, however, acknowledged in a terse sta...

Google on Tuesday released an update for Chrome web browser for Windows, Mac, and Linux, with a total of seven security fixes, including one flaw for which it says an exploit exists in the wild. Tracked as CVE-2021-21224 , the flaw concerns a type confusion vulnerability in V8 open-source JavaScript engine that was reported to the company by security researcher Jose Martinez on April 5 According to security researcher  Lei Cao , the bug [ 1195777 ] is triggered when performing integer data type conversion, resulting in an out-of-bounds condition that could be used to achieve arbitrary memory read/write primitive. "Google is aware of reports that exploits for CVE-2021-21224 exist in the wild," Chrome's Technical Program Manager Srinivas Sista  said  in a blog post. The update comes after proof-of-concept (PoC) code exploiting the flaw published by a researcher named " frust " emerged on April 14 by taking advantage of the fact that the issue was addressed...

I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...
