Google fixes record number of Chrome bugs in June using AI tools, surpassing two years of previous patches

Google announces it patched a record 1,072 Chrome security bugs in June 2026 using internal AI tools like Gemini, surpassing the 1,036 fixes from the previous two years combined. This surge aligns with industry trends, as Microsoft also fixed a record 570 flaws in July 2026 using AI. Meanwhile, Apple maintains a steady patching pace of 482 bugs in 2026, showing no exponential increase. Chrome's Doug Turner notes that LLMs have fundamentally shifted cybersecurity economics.

Chrome AI bug fixes

• ▪The 1,072 Chrome security bugs patched in June 2026 exceeded the 1,036 bugs patched in the previous 23 versions of Chrome over the prior two years.
• ▪Google patched 1,072 security bugs in Chrome versions 149 and 150, both released in June 2026, using internal artificial intelligence tools.

Exponential vulnerability discovery rates

• ▪A chart in a Google white paper illustrates an exponential increase in the number of security bugs fixed in released versions of Chrome.
• ▪Cybersecurity experts predicted that artificial intelligence-powered systems would find an exponentially increasing number of software bugs, forcing defenders to adopt artificial intelligence.

Microsoft Patch Tuesday records

• ▪Microsoft attributed its record-breaking number of security patches in July 2026 to the company's use of artificial intelligence.
• ▪Microsoft patched a record 570 security flaws across its product lines in July 2026 as part of its monthly "Patch Tuesday" updates.

Apple patching pace comparison

• ▪Apple's 2026 security patching pace does not show an exponential increase and is roughly equal to the number of bugs Apple patched in 2015.
• ▪Apple patched 482 security bugs in 2026, which is roughly on pace to equal or surpass the number of bugs the company fixed in 2025.

LLM cybersecurity economics

• ▪Google utilizes its Gemini artificial intelligence models to preemptively identify and fix security vulnerabilities in the Chrome browser.
• ▪Chrome Director of Engineering Doug Turner stated that large language models have fundamentally shifted cybersecurity economics by automating vulnerability discovery on an industrial scale.
