Description Sandro Bonazzola 2023-04-17 07:32:29 UTC
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   **************************

Se ci credi ModemManager dovrebbe essere consentito execmem accesso ai processi etichettati modemmanager_t per impostazione predefinita.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
consentire questo accesso per ora eseguendo:
# ausearch -c 'ModemManager' --raw | audit2allow -M my-$MODULE_NOME
# semodule -X 300 -i miei-ModemManager.pp
