:SELinux is preventing /usr/sbin/lldpad from using the 'sys_module' capabilities.
:
:*****  Plugin sys_module (99.5 confidence) suggests  *************************
:
:If you do not believe that /usr/sbin/lldpad should be attempting to modify the kernel by loading a kernel module.
:Then a process might be attempting to hack into your system.
:Do
:contact your security administrator and report this issue.
:
:*****  Plugin catchall (1.49 confidence) suggests  ***************************
:
:If you believe that lldpad should have the sys_module capability 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:
:# grep lldpad /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp
