Google has launched an emergency safety replace for its Chrome internet browser to handle a high-severity zero-day vulnerability that’s being actively exploited within the wild.
Customers are strongly urged to replace their browsers instantly to guard towards potential assaults. The vulnerability, tracked as CVE-2025-10585, is the newest in a sequence of zero-days found and patched in Chrome this yr.
The brand new secure channel model has been up to date to 140.0.7339.185/.186 for Home windows and Mac, and 140.0.7339.185 for Linux.
Google has said that the replace can be rolling out to all customers over the approaching days and weeks. To mitigate the rapid menace, customers ought to manually set off the replace course of to make sure they’re protected.
Zero-Day Vulnerability Exploited
The actively exploited vulnerability, CVE-2025-10585, is a Sort Confusion flaw within the V8 JavaScript and WebAssembly engine.
Sort confusion bugs happen when a program allocates a useful resource or object utilizing one sort however later accesses it with a distinct, incompatible sort. This may result in logical errors, reminiscence corruption, and in the end, arbitrary code execution.
A profitable exploit may enable a distant attacker to flee the browser’s safety sandbox by tricking a consumer into visiting a specifically crafted, malicious webpage.
The vulnerability was reported on September 16, 2025, by Google’s personal Risk Evaluation Group (TAG), which usually finds zero-days being utilized in focused assaults by refined menace actors.
Different Vulnerabilities
Along with the zero-day, this safety replace addresses three different high-severity vulnerabilities found by exterior safety researchers.
The primary, CVE-2025-10500, is a use-after-free vulnerability in Daybreak, a graphics abstraction layer. The second, CVE-2025-10501, can also be a use-after-free flaw, discovered within the WebRTC element, which allows real-time communication.
The third vulnerability, CVE-2025-10502, is a heap buffer overflow in ANGLE, a graphics engine translation layer. Use-after-free and heap overflow vulnerabilities may result in reminiscence corruption and arbitrary code execution.
Google has awarded bug bounty funds of $15,000 and $10,000 for the invention of two of those flaws.
Given the affirmation of lively exploitation, the chance to unpatched methods is important. All Google Chrome customers on Home windows, macOS, and Linux are suggested to replace their browsers to the newest model immediately.
To test your Chrome model and apply the replace, navigate to the “Assist” menu and choose “About Google Chrome.” The browser will mechanically test for and obtain the newest replace, after which a restart can be required to use the patch.
Google is presently proscribing entry to the bug particulars and hyperlinks associated to CVE-2025-10585 to stop additional abuse whereas the patch is being rolled out to nearly all of its consumer base.
In 2025, Google patched a number of actively exploited zero-day vulnerabilities in its Chrome internet browser, requiring customers to replace their software program promptly to remain protected.
