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

*****  Plugin allow_execmem (91.4 confidence) suggests   *********************

If this issue occurred during normal system operation.
Then this alert could be a serious issue and your system could be compromised.
Do
contact your security administrator and report this issue

*****  Plugin catchall (9.59 confidence) suggests   **************************

Si vous pensez que ModemManager devrait être autorisé à accéder execmem sur les processus étiquetés modemmanager_t par défaut.
Then vous devriez rapporter ceci en tant qu'anomalie.
Vous pouvez générer un module de stratégie local pour autoriser cet accès.
Do
autoriser cet accès pour le moment en exécutant :
# ausearch -c "ModemManager" --raw | audit2allow -M my-ModemManager
# semodule -X 300 -i my-ModemManager.pp
