Description of problem: I have upgraded 2 different Fedora 37 systems to F38 using dnf system-upgrade, one is a virtual machine the other bare metal, and both are showing this as well as another SELinux denial on boot. 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 ************************** If you believe that ModemManager should be allowed execmem access on processes labeled modemmanager_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 '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 Unknown [ process ] Source ModemManager Source Path ModemManager Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-38.12-1.fc38.noarch Local Policy RPM selinux-policy-targeted-38.12-1.fc38.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.2.14-300.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Mon May 1 00:55:28 UTC 2023 x86_64 Alert Count 1 First Seen 2023-05-08 15:20:14 EDT Last Seen 2023-05-08 15:20:14 EDT Local ID 16ed2c31-1457-4166-ba38-d2873690bb29 Raw Audit Messages type=AVC msg=audit(1683573614.710:146): avc: denied { execmem } for pid=1064 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-38.12-1.fc38.noarch Additional info: reporter: libreport-2.17.9 package: selinux-policy-targeted-38.12-1.fc38.noarch component: selinux-policy hashmarkername: setroubleshoot type: libreport kernel: 6.2.14-300.fc38.x86_64 reason: SELinux is preventing ModemManager from using the 'execmem' accesses on a process.
