Description Ian Laurie 2022-09-03 06:54:36 UTC
Description of problem:
First login to Xfce Security Lab freshly installed from 20220831.n.0.
SELinux is preventing pmdakvm from 'search' accesses on the directory /sys/kernel/tracing.

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

If you believe that pmdakvm should be allowed search access on the tracing directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'pmdakvm' --raw | audit2allow -M my-pmdakvm
# semodule -X 300 -i my-pmdakvm.pp
