vuln-verfiy can't pass because the patch has not backported currently to 6.12 tree

Hi, vuln-verify should now work when the patches haven't been backported but it looks like your exploit doesn't reproduce at all on LTS and COS. You will need to fix that before this becomes eligible for a reward. Thank you!
