***** Plugin catchall (100. confidence) suggests **************************
If you believe that mongod should be allowed read access on the memory.limit_in_bytes 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 'mongod' --raw | audit2allow -M my-mongod
# semodule -X 300 -i my-mongod.pp
