Google Releases Chrome 157 With Fixes for 213 Security Vulnerabilities

Google has released Chrome 157 for Windows, macOS, and Linux, which addresses 213 security vulnerabilities, including seven serious problems. The update, which was announced on November 3, 2026, fixes security issues in several areas of the browser, including graphics, memory management, and access controls. Google claims users will receive the stable update in the coming days and weeks.

The most recent Google Chrome security update is essential because some of the repaired vulnerabilities could pose security threats if abused. Users are encouraged to update to the most recent version to keep their browsers secure.

Among the seven critical vulnerabilities, two are linked to buffer overflow flaws in Dawn, Chrome's technology for supporting WebGPU graphics. These vulnerabilities are tracked as CVE-2026-121156 and CVE-2026-121247. A buffer overflow occurs when software attempts to store more data in a memory area than it can handle. This can cause the program to behave unexpectedly and potentially create security vulnerabilities that attackers could exploit.

Another critical vulnerability, CVE-2026-121229, affects ANGLE, a component responsible for graphics processing. The remaining four critical flaws involve use-after-free errors in WebGL, Prerender, Geometry and Core. These errors occur when software continues accessing a section of memory after it has already been released, potentially allowing attackers to interfere with the browser's operation.

In addition to these critical vulnerabilities, Chrome 157 fixes several high-severity security flaws affecting BackgroundFetch, V8, PDFium and Media. These components handle various browser functions, including background data transfers, JavaScript execution, PDF viewing and media playback. Security weaknesses in these areas could put users at risk if exploited.

Google has not verified if the vulnerabilities addressed in Chrome 157 are being utilized in ongoing attacks. However, if vulnerabilities are left unpatched, users may be at risk if attackers manage to take advantage of them.

Additionally, until more people receive the patches, the corporation has restricted access to certain technical details. This lessens the possibility of attackers utilizing the data before people upgrade their browsers.

The patched versions are 157.0.8103.38 for Linux and 157.0.8103.38/.39 for Windows and macOS. Users should check their Chrome version and install the latest available update to improve browser security.
