Long running commands oc exec and oc rsh are terminated prematurely with 0 exit code during OCP cluster upgrade

 Client Version: 4.19.0
Kustomize Version: v5.5.0
Server Version: 4.19.6
Kubernetes Version: v1.32.7 
    

    Always

    1.Install OCP 4.19.6
    2.start `oc exec -n openshift-monitoring prometheus-k8s-0 -- sleep 99999` or use any other pod
    3.Start cluster upgrade process to 4.19.9
    

    oc exec is terminated prematurely with 0 exit code during OCP cluster upgrade

    oc exec should exit with exit code > 0

    Both oc exec and oc rsh are affected. I tried to find a smaller reproducer e.g. applying ImageDigestMirrorSet resource which triggers cluster reconciliation but in that case the commend exits as expected with: "command terminated with exit code 137"
