NixOS uses VEX to automate vulnerability triage
What happened
On October 12, the Hacker News front page covered NixOS using VEX (Vulnerability Exploitability eXchange) documents for automated vulnerability triage, against a surge in LLM-assisted vulnerability reports. The report notes that SBOM-based scanning produces many false positives for CVEs unrelated to how a program is actually used. For example, a Go program includes golang.org/x/text v0.38.0, and the two vulnerabilities in that version map to code the program never calls, which govulncheck can pinpoint. NixOS uses VEX documents to handle this vulnerability information and support automated triage.

面对 LLM 辅助漏洞报告激增，NixOS 借助 VEX（Vulnerability Exploitability eXchange）文档实现自动化漏洞分诊。基于 SBOM 的扫描会误报大量无关 CVE，如 Go 程序中 golang.org/x/text v0.38.0 的两个漏洞实际未被调用，而 govulncheck 可精准定位。
