Google Says AI Helped Fix More Chrome Bugs in June Than in the Previous Two Years

Google says its internal AI tools helped the company patch more security vulnerabilities in Chrome during June than it fixed across the previous two years combined.

The company announced Thursday that the last two Chrome releases, both issued in June, included fixes for 1,072 security bugs.

That total exceeds the 1,036 vulnerabilities Google patched across the previous 23 Chrome versions released over the past two years.

AI is accelerating vulnerability discovery

Since the rise of large language models, cybersecurity researchers have predicted that AI would dramatically increase the speed and scale of vulnerability discovery, forcing defenders to adopt AI to keep pace with attackers.

Google says the latest Chrome figures suggest that prediction is beginning to materialise.

As part of a white paper outlining how it uses AI to identify and fix software flaws more quickly, the company published a chart showing a sharp increase in security fixes.

For comparison, Chrome 126 was released in June 2024, while Chrome 149 and Chrome 150—the two most recent milestones—were released last month.

Google credits Gemini for improving security

Doug Turner, Chrome’s Director of Engineering, said large language models have fundamentally changed how cybersecurity teams approach vulnerability detection.

“LLMs have fundamentally shifted the economics of cybersecurity, transforming vulnerability discovery into an automated, industrial-scale operation,” Turner said.

“By applying models like Gemini, we are preemptively fixing vulnerabilities, outpacing our adversaries and making Chrome safer with every update,” he added.

Microsoft reports a similar trend

Google is not alone in seeing AI contribute to a surge in vulnerability discoveries.

Earlier this month, Microsoft said it fixed a record 570 security vulnerabilities across its products during its monthly Patch Tuesday release.

The company also pointed to its use of AI as a key reason for the increase in identified and patched security flaws. Apple’s numbers remain relatively stable.

Apple, however, has not experienced the same sharp rise in reported bug fixes.

According to an independent count of vulnerabilities addressed in its products, Apple has fixed 482 bugs so far in 2026.

That places the company roughly on pace to match or slightly exceed lastyear’ss total, while remaining broadly similar to the number of vulnerabilities Apple addressed in 2015.

The differing figures suggest AI-assisted vulnerability discovery is accelerating rapidly for some software vendors, even if the pace varies across the industry.
