Segmentation fault in actions-runner 2.331.0 on Rocky Linux 9.7

[daniel-widrick]

Describe the bug
When attempting to run ephemeral GitHub Actions runners using the ghcr.io/actions/actions-runner:2.331.0 image on Rocky Linux 9.7 hosts, the runner immediately crashes with a segmentation fault (core dumped). Reverting to 2.330.0 resolves the issue.

To Reproduce
Steps to reproduce the behavior:

1. Deploy gha-runner-scale-set-controller:0.13.1 in a Kubernetes cluster.
2. Launch ephemeral runner pods using ghcr.io/actions/actions-runner:2.331.0.
3. Observe runner pod logs:

[RUNNER 2026-01-14 16:09:02Z INFO RunnerServer] Establish connection with 100 seconds timeout.
[RUNNER 2026-01-14 16:09:02Z INFO GitHubActionsService] Starting operation Location.GetConnectionData
/home/runner/run-helper.sh: line 36:    14 Segmentation fault      (core dumped) "$DIR"/bin/Runner.Listener run $*
Exiting with unknown error code: 139
Exiting runner...

Expected behavior
Runner should start and connect to GitHub without crashing

What's not working?

dmesg from host:

We have to upgrade to ubuntu:24.04 as our base image, my guess is that's not compat with your Kubernetes
