I checked this on several of my systems and unfortunately I found that many KDE processes do have rwx memory mappings. I chose to report this bug against the kded package because it is one of the most fundamental affected KDE process I found. However, the problem seems to be more general in KDE. I apologize in advance for not finding a better software package to report this problem. Version-Release number of selected component (if applicable): Fedora 30 packages updated today. How reproducible: always Steps to Reproduce: 1. Log in Plasma 2. Run the following command: $ grep rwx /proc/$(pidof kded5)/maps Actual results: $ grep rwx /proc/$(pidof kded5)/maps 7f68d7c2a000-7f68d7c3a000 rwxp 00000000 00:00 0 Expected results: No output Additional info: According to comments in this bug report: https://bugs.kde.org/show_bug.cgi?id=407496 other Linux distributions do not have the same problem.
