Description parasail_stanf 2026-06-09 07:05:27 UTC
Description of problem:
SELinux is preventing systemd-coredum from using the 'signull' accesses on a process.

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

If you believe that systemd-coredum should be allowed signull access on processes labeled container_runtime_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 'systemd-coredum' --raw | audit2allow -M my-systemdcoredum
# semodule -X 300 -i my-systemdcoredum.pp
