[release-4.13] OCPBUGS-79795: Address CVE-2026-33186

[ocp-sustaining-admins]

This is an automated PR from the ARC system.

A fix for CVE-2026-33186 is included in google.golang.org/grpc@v1.79.3, however that version requires a Go toolchain newer than supported on branch release-4.13 (max Go for this component: 1.19).

To address this, a backport of the fix is provided in github.com/openshift-sustaining/grpc-go@v1.64.1-sec.1, applied via go mod edit -replace.

Go version used: go1.19.13

Replace applied: google.golang.org/grpc → github.com/openshift-sustaining/grpc-go@v1.64.1-sec.1

Modules affected: .

The commands used to generate this PR were:

go mod edit -replace google.golang.org/grpc=github.com/openshift-sustaining/grpc-go@v1.64.1-sec.1
go mod tidy
go mod vendor

A member of the Red Hat Openshift Sustaining Team will review the PR and take appropriate action.

Common PR issues and how to fix them:

1. Title needs to be changed:
   This might be needed if a PR references multiple Jira issues and some of them have been closed as duplicates.
   Use /retitle <NEW TITLE> command from openshift-ci bot
   openshift-ci bot commands

2. verify-commits check is failing:
   Commits need to be in the format UPSTREAM: <carry | drop | PR NUMBER>: <commit message>. You can do this by cloning the ARC fork and using git commit --amend -m <commit message>
   verify-commits documentation

Hi @ocp-sustaining-admins. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Tip

We noticed you've done this a few times! Consider joining the org to skip this step and gain /lgtm and other bot rights. We recommend asking approvers on your previous PRs to sponsor you.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
