on f36 i never received any selinux alerts but after an upgrade to f37 i get them all the time and this is one of them that shows up in the list of many(mostly snap related): SELinux is preventing libvirt_leasesh from using the execmem access 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 libvirt_leasesh should be allowed execmem access on processes labeled dnsmasq_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 'libvirt_leasesh' --raw | audit2allow -M my-libvirtleasesh # semodule -X 300 -i my-libvirtleasesh.pp Additional Information: Source Context system_u:system_r:dnsmasq_t:s0-s0:c0.c1023 Target Context system_u:system_r:dnsmasq_t:s0-s0:c0.c1023 Target Objects Unknown [ process ] Source libvirt_leasesh Source Path libvirt_leasesh Port <Unknown> Host kinghat-thinkpad Source RPM Packages Target RPM Packages SELinux Policy RPM selinux-policy-targeted-37.16-1.fc37.noarch Local Policy RPM selinux-policy-targeted-37.16-1.fc37.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name kinghat-thinkpad Platform Linux kinghat-thinkpad 6.0.15-300.fc37.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Dec 21 18:33:23 UTC 2022 x86_64 x86_64 Alert Count 8 First Seen 2022-12-13 11:56:47 CST Last Seen 2022-12-26 11:42:26 CST Local ID 541a0840-21f2-4db9-a9a1-dfa54addbfb4 Raw Audit Messages type=AVC msg=audit(1672076546.115:725): avc: denied { execmem } for pid=28915 comm="libvirt_leasesh" scontext=system_u:system_r:dnsmasq_t:s0-s0:c0.c1023 tcontext=system_u:system_r:dnsmasq_t:s0-s0:c0.c1023 tclass=process permissive=0 Hash: libvirt_leasesh,dnsmasq_t,dnsmasq_t,process,execmem
