The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning about a high-severity zero-day vulnerability in Google Chrome that is being actively exploited in attacks.<\/p>\n
The vulnerability, tracked as CVE-2025-10585<\/a>, has been added to CISA\u2019s Known Exploited Vulnerabilities (KEV) catalog, signaling an urgent need for users and administrators to take action.<\/p>\n Google has confirmed it is aware that an exploit for this flaw exists in the wild and has released security updates to address the threat.<\/p>\n The vulnerability is a type confusion weakness within Chrome\u2019s V8 JavaScript and WebAssembly engine. A type confusion flaw (CWE-843) occurs when a program attempts to access a resource with an incompatible type, causing it to misinterpret the data.<\/p>\n This can lead to memory corruption, which an attacker can leverage to crash the browser or, more critically, execute arbitrary code on the affected system.<\/p>\n The flaw was discovered and reported by Google\u2019s own Threat Analysis Group (TAG) on September 16, 2025.<\/p>\n While Google has not disclosed technical details about the specific attacks or the threat actors involved, this is a standard practice to prevent wider exploitation before users have a chance to apply the necessary patches.<\/p>\n This marks the sixth Chrome zero-day vulnerability that has been actively exploited in 2025, highlighting a persistent trend of attackers targeting browser vulnerabilities.<\/p>\n In 2025, Google addressed multiple zero-day vulnerabilities in its Chrome web browser that were actively exploited in the wild. These flaws required urgent updates to protect users from potential attacks.<\/p>\n The table below details the Chrome zero-day vulnerabilities that have been discovered and patched throughout the year.<\/p>\nUnderstanding the V8 Type Confusion Flaw<\/strong><\/h2>\n
