Description lukas.ebner 2023-04-27 09:45:30 UTC

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   **************************

Wenn Sie denken, dass es ModemManager standardmäßig erlaubt sein sollte, execmem Zugriff auf modemmanager_t Prozesse zu erhalten.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
zugriff jetzt erlauben, indem Sie die nachfolgenden Befehle ausführen:
# ausearch -c 'ModemManager' --raw | audit2allow -M my-ModemManager
# semodule -X 300 -i my-ModemManager.pp
