Description thedatum+bz 2020-05-08 18:29:48 UTC 
Description of problem:
Occurred during a kernel upgrade.
SELinux is preventing systemd-modules from 'open' accesses on the file /sys/firmware/efi/efivars/SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that systemd-modules should be allowed open access on the SecureBoot-8be4df61-93ca-11d2-aa0d-00e098032b8c file 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 'systemd-modules' --raw | audit2allow -M my-systemdmodules
# semodule -X 300 -i my-systemdmodules.pp
