Hi Greg, Salvatore,

When I have submitted this patch for review, at that time, 6.1.52 was not released.

It will be good if you can share me guideline or details like how I can share CVE fix patch to upstream for review like what details I need to include in patch for review so from next time, we can save time in query discussion.

Regards,
Deepak
