+Subject: [PATCH] [release-branch.go1.25] all: update x/net to a9171bc8
+
+Fixes #78477
+
+Change-Id: I0a4c8e25f569fc1bfb8ac39ff728bfe7300b751f

+CVE: CVE-2026-33814
+Upstream-Status: Backport [https://github.com/golang/go/commit/9024c3f6b150fb1349d8a5dc5e9aa31d7896f67f]
+
+Backport Changes:
+- Omitted src/go.mod, src/go.sum, and src/vendor/modules.txt because
+  their x/net version updates are not required for this focused backport.
+- Omitted removal of the SETTINGS_ENABLE_CONNECT_PROTOCOL-specific
+  s.Valid call because Go 1.22 does not contain that setting case; validation
+  is added at the start of the settings callback instead.
+
+(cherry picked from commit 9024c3f6b150fb1349d8a5dc5e9aa31d7896f67f)
