Description of problem:
SELinux is preventing check from 'mmap_zero' accesses on the memprotect labeled spc_t.

*****  Plugin mmap_zero (53.1 confidence) suggests   *************************

If you do not think check should need to mmap low memory in the kernel.
Then you may be under attack by a hacker, this is a very dangerous access.
Do
contact your security administrator and report this issue.

*****  Plugin catchall_boolean (42.6 confidence) suggests   ******************

If you want to allow mmap to low allowed
Then you must tell SELinux about this by enabling the 'mmap_low_allowed' boolean.

Do
setsebool -P mmap_low_allowed 1

*****  Plugin catchall (5.76 confidence) suggests   **************************

If you believe that check should be allowed mmap_zero access on memprotect labeled spc_t 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 'check' --raw | audit2allow -M my-check
# semodule -X 300 -i my-check.pp
