Google has released a Chrome Stable update that addresses 37 security vulnerabilities in the desktop browser. The update was announced on October 13, 2026, and is being distributed to Windows, macOS and Linux users over the coming days and weeks.
What the update fixes
Google’s release notes list a range of security issues affecting browser components, including several critical and high-severity flaws. The disclosed examples include memory-safety problems such as buffer overflows and use-after-free vulnerabilities in areas of the browser and related components. A vulnerability may allow a malicious page or other attack path to trigger a crash, corrupt memory or potentially enable more serious compromise depending on the conditions.
Google does not always publish every technical detail immediately. The company says some bug information and links can remain restricted until a majority of users have received a fix, particularly when disclosure could put people at risk or when a third-party component is involved.
How to update Chrome
On desktop, open Chrome and select the three-dot menu. Go to Help → About Google Chrome. Chrome will check for updates and begin downloading an available release. Relaunch the browser when prompted to finish the installation. The rollout is gradual, so the exact version displayed can depend on the operating system and update channel.
Why installing browser updates matters
Browsers process content from many sources, including websites, ads, documents, video streams and web applications. Security updates reduce the window in which attackers can exploit a known flaw. Keeping the browser updated is one of the simplest ways to improve everyday online security, alongside using a supported operating system, avoiding suspicious downloads and enabling account protections.
Businesses should also make sure managed Chrome installations receive updates according to their organisation’s patching policies. Users who cannot update may be using an outdated operating system or a managed device that requires administrator approval.
Official release details
Google’s release notes describe Chrome version 155.0.8059.79/.80 for Windows and Mac and 155.0.8059.79 for Linux, with rollout timing varying by platform. Check the official Chrome Releases blog for the latest version details and security notes.
