Google、AI活用で6月のChromeバグ修正数が過去2年分を上回る

With help from its internal AI tools, Google says it has patched more security flaws in its Chrome browser in the last month than in the past two years combined.

The tech giant announced on Thursday that it has fixed a whopping 1,072 security bugs in the last two versions of Chrome, both released in June. That is more than the number of bugs patched in the previous 23 versions released over the last two years, which totalled 1,036 fixes.

Ever since the advent of LLMs, cybersecurity experts have warned that AI-powered systems would find an increasingly and exponentially enormous amount of bugs, forcing defenders to also use AI to get ahead of malicious hackers.

That prediction is starting to become true, and it’s backed by real data.

A chart published by Google, which the company revealed as part of a white paper on the company’s efforts to use AI to find flaws and patch them faster, shows the exponential increase. For context, Chrome’s 126 was released in June 2024, while the latest two Chrome releases, Chrome 149 and 150, were released last month. Google calls each version a “milestone.”

Doug Turner, Chrome’s director of engineering, told TechCrunch in a statement that LLMs have “fundamentally shifted the economics of cybersecurity, transforming vulnerability discovery into an automated, industrial-scale operation.”

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

Google is not the only company seeing this trend.

Earlier this month, Microsoft announced that it had patched a record 570 security flaws across its product lines as part of its monthly round of scheduled patches — colloquially known as “Patch Tuesday.” Microsoft cited its own use of AI to explain the sudden jump in bug fixes.

Apple, meanwhile, does not appear to be registering the same exponential increase. According to an independent count of bugs fixed by in its products, Apple has patched 482 bugs in 2026, which is roughly on pace to equal or surpass the number of fixed buts from last year, and also roughly equal from the number of bugs that Apple patched in 2015.

TechCrunch reached out to Apple for comment, but did not hear back.
