Description of problem:
SELinux is preventing brcupsconfcl1 from using the 'execmem' accesses on a process.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

If you want to allow cups to execmem
Then you must tell SELinux about this by enabling the 'cups_execmem' boolean.

Do
setsebool -P cups_execmem 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that brcupsconfcl1 should be allowed execmem access on processes labeled cupsd_t 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:
# ausearch -c 'brcupsconfcl1' --raw | audit2allow -M my-brcupsconfcl1
# semodule -X 300 -i my-brcupsconfcl1.pp
