Claude Code Found a Linux Vulnerability Hidden for 23 Years (mtlynch.io)

Article summary

Nicholas Carlini, a research scientist at Anthropic, used Claude Code to find multiple remotely exploitable security vulnerabilities in the Linux kernel, including one that had been hidden for 23 years. The vulnerabilities were discovered by pointing Claude Code at the Linux kernel source code and asking it to find security vulnerabilities. Carlini found hundreds of potential bugs, but the manual step of validating them is a bottleneck. The discovery highlights the potential of large language models in finding security vulnerabilities.

Main themes

• Linux kernel vulnerabilities
• AI-powered security research
• Cost of AI services
• Code review and validation
• Security threats and exploits

What commenters say

• The cost of using AI services like Claude Code is prohibitively expensive for many companies, despite the potential benefits of finding security vulnerabilities.
• The cost of AI services is currently relatively low, and individuals and companies should take advantage of them while they last.
• Measuring the productivity and cost-effectiveness of AI services is difficult, as it depends on various factors and may not be directly correlated with monetary gain.
• The use of AI services like Claude Code may introduce new vulnerabilities, rather than just discovering existing ones.
• The discovery of security vulnerabilities using AI services like Claude Code has significant implications for national security and intelligence agencies.
• The development of open-source AI models may mitigate the costs associated with proprietary AI services and provide a more sustainable solution.
• The pressure from top labs competing with each other and the availability of open models will keep prices for AI services at a reasonable level.
• The effectiveness of AI services in finding security vulnerabilities may lead to a shift in the way companies approach code review and validation.
