Description of problem:

As a defense against machine code injection made possible by buffer overflow bugs, most Linux distributions have worked over the years to remove as many rwx memory mappings as possible in processes.

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
