Summary

Cherry-pick of #8551 to official/vv20260107.

Bumps the Go toolchain and golang.org/x/net to address upstream CVEs:

Vulnerability CVE Component Fixed by
net/mail DoS via crafted addresses CVE-2026-39820 net/mail (stdlib) Go 1.25.10
cmd/go pack subcommand directory traversal CVE-2026-39817 cmd/go (stdlib) Go 1.25.10
HTTP/2 + IPv6 host parsing fixes (various, see x/net release notes) golang.org/x/net v0.55.0

Why bump to Go 1.25 (and not a 1.24.x patch)

Go 1.24 reached EOL in February 2026 and does NOT receive security backports. go1.25.10 is the only release stream that contains these fixes.

golang.org/x/net v0.51.0+ also requires go 1.25.0 in its own go.mod, so the Go bump is required regardless.

Verification

  • go mod tidy succeeds for every module in the branch.
  • go build ./... clean across every module.
  • PR CI must pull go 1.25 runners.

Release plan

Once merged, two tags are pushed off the resulting commit:

  • v0.v20260107.<N+1> (AgentBaker module)
  • aks-node-controller/v0.v20260107.<N+1> (aks-node-controller submodule)
