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

Comment:

This error occurred on starting a virtual machine and many of these "access policy" errors occurred in the past after updating to Fedora 37.
