A govulncheck pass against the current module and toolchain reports standard-library vulnerabilities in the Go version this repo targets today.

What I hit locally:

  • go.mod currently declares go 1.26.1
  • govulncheck ./... reported the following reachable stdlib advisories:
    • GO-2026-4947 in crypto/x509, fixed in Go 1.26.2
    • GO-2026-4946 in crypto/x509, fixed in Go 1.26.2
    • GO-2026-4870 in crypto/tls, fixed in Go 1.26.2
    • GO-2026-4866 in crypto/x509, fixed in Go 1.26.2

Representative traces from the scan reached:

  • main.go:71
  • internal/firecracker/api.go:230

Expected behavior:

  • The public host daemon repo should target a Go toolchain version with these standard-library fixes.

Suggested follow-up:

  • Bump the declared Go version and CI/runtime toolchain to 1.26.2 or newer.
  • Add govulncheck to the validation path so future stdlib advisories are caught quickly.
A `govulncheck` pass against the current module and toolchain reports standard-library vulnerabilities in the Go version this repo targets today. What I hit locally: - `go.mod` currently declares `go 1.26.1` - `govulncheck ./...` reported the following reachable stdlib advisories: - `GO-2026-4947` in `crypto/x509`, fixed in Go `1.26.2` - `GO-2026-4946` in `crypto/x509`, fixed in Go `1.26.2` - `GO-2026-4870` in `crypto/tls`, fixed in Go `1.26.2` - `GO-2026-4866` in `crypto/x509`, fixed in Go `1.26.2` Representative traces from the scan reached: - `main.go:71` - `internal/firecracker/api.go:230` Expected behavior: - The public host daemon repo should target a Go toolchain version with these standard-library fixes. Suggested follow-up: - Bump the declared Go version and CI/runtime toolchain to `1.26.2` or newer. - Add `govulncheck` to the validation path so future stdlib advisories are caught quickly.
