Kirill A. Shutemov ab676b7d6f pagemap: do not leak physical addresses to non-privileged userspace ... As pointed by recent post[1] on exploiting DRAM physical imperfection, /proc/PID/pagemap exposes sensitive information which can be used to do attacks. This disallows anybody without CAP_SYS_ADMIN to read the pagemap.
