Description of problem: Start the system. 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 Additional Information: Source Context system_u:system_r:modemmanager_t:s0 Target Context system_u:system_r:modemmanager_t:s0 Target Objects Unbekannt [ process ] Source ModemManager Source Path ModemManager Port <Unbekannt> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-39.5-1.fc39.noarch Local Policy RPM selinux-policy-targeted-39.5-1.fc39.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.8.4-200.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Apr 4 20:45:21 UTC 2024 x86_64 Alert Count 1 First Seen 2024-04-12 16:22:33 CEST Last Seen 2024-04-12 16:22:33 CEST Local ID b7800f29-e072-4e20-a46c-1435b99140e4 Raw Audit Messages type=AVC msg=audit(1712931753.85:122): avc: denied { execmem } for pid=4513 comm="ModemManager" scontext=system_u:system_r:modemmanager_t:s0 tcontext=system_u:system_r:modemmanager_t:s0 tclass=process permissive=0 Hash: ModemManager,modemmanager_t,modemmanager_t,process,execmem Version-Release number of selected component: selinux-policy-targeted-39.5-1.fc39.noarch Additional info: reporter: libreport-2.17.11 reason: SELinux is preventing ModemManager from using the 'execmem' accesses on a process. package: selinux-policy-targeted-39.5-1.fc39.noarch component: selinux-policy hashmarkername: setroubleshoot type: libreport kernel: 6.8.4-200.fc39.x86_64 comment: Start the system. component: selinux-policy
