*** This bug has been marked as a duplicate of bug 730179 *** SELinux is preventing /usr/lib/chromium-browser/chromium-browser from execmod access on the file /usr/lib/chromium-browser/chromium-browser.
***** Plugin allow_execmod (91.4 confidence) suggests **********************
If you want to allow chromium-browser to have execmod access on the chromium-browser file
Then you need to change the label on '/usr/lib/chromium-browser/chromium-browser'
Do
# semanage fcontext -a -t textrel_shlib_t '/usr/lib/chromium-browser/chromium-browser'
# restorecon -v '/usr/lib/chromium-browser/chromium-browser'
***** Plugin catchall (9.59 confidence) suggests ***************************
If you believe that chromium-browser should be allowed execmod access on the chromium-browser file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep chromium-browse /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
