Description of problem:

I am getting this notification. I am not sure what this is. Is this a bug? Has SELinux identified malware?

SELinux is preventing find from read access on the directory dma_heap.

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

If you believe that find should be allowed read access on the dma_heap 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 'find' --raw | audit2allow -M my-find
# semodule -X 300 -i my-find.pp
