Description of problem: Getting a lot of denials like this trying to run Slack and Matrix flatpaks on Rawhide lately. SELinux is preventing element-desktop from using the 'execheap' accesses on a process. ***** Plugin allow_execheap (53.1 confidence) suggests ******************** If you do not think element-desktop should need to map heap memory that is both writable and executable. Then you need to report a bug. This is a potentially dangerous access. Do contact your security administrator and report this issue. ***** Plugin catchall_boolean (42.6 confidence) suggests ****************** If you want to allow selinuxuser to execheap Then you must tell SELinux about this by enabling the 'selinuxuser_execheap' boolean. Do setsebool -P selinuxuser_execheap 1 ***** Plugin catchall (5.76 confidence) suggests ************************** If you believe that element-desktop should be allowed execheap access on processes labeled unconfined_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 'element-desktop' --raw | audit2allow -M my-elementdesktop # semodule -X 300 -i my-elementdesktop.pp Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0- s0:c0.c1023 Target Context unconfined_u:unconfined_r:unconfined_t:s0- s0:c0.c1023 Target Objects Unknown [ process ] Source element-desktop Source Path element-desktop Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-41.12-1.fc41.noarch Local Policy RPM selinux-policy-targeted-41.12-1.fc41.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 6.10.0-64.fc41.x86_64 #1 SMP PREEMPT_DYNAMIC Mon Jul 15 15:28:59 UTC 2024 x86_64 Alert Count 1064 First Seen 2023-12-16 09:08:27 PST Last Seen 2024-08-06 04:49:03 PDT Local ID 86e0cd89-adb4-42f5-a174-d8ced956b26e Raw Audit Messages type=AVC msg=audit(1722944943.969:4083): avc: denied { execheap } for pid=302530 comm="slack" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process permissive=0 Hash: element-desktop,unconfined_t,unconfined_t,process,execheap Version-Release number of selected component: selinux-policy-targeted-41.12-1.fc41.noarch Additional info: reporter: libreport-2.17.15 reason: SELinux is preventing element-desktop from using the 'execheap' accesses on a process. package: selinux-policy-targeted-41.12-1.fc41.noarch component: selinux-policy hashmarkername: setroubleshoot type: libreport kernel: 6.10.0-64.fc41.x86_64 comment: Getting a lot of denials like this trying to run Slack and Matrix flatpaks on Rawhide lately. component: selinux-policy
