Tests on Ubuntu 20.04 kernel 5.4.0-96-generic show that CAP_DAC_OVERRIDE is missing from the list. Unfortunately, this capability guards quite a lot. 2. If the process lack privileges, it will see /proc/self/pagemap zero-filled. I assume you understand that using physical addresses allows to effectively bypass any OS restrictions. Please tell if CAP_DAC_OVERRIDE helps, I will update the doc.
