Cross-filed case 01710942 on the Red Hat customer portal, which also includes the sosreport of the system (if needed). Cross-filed case 01731427 (for another customer) on the Red Hat customer portal, which also includes the sosreport of the system (if needed). Bug #1398338 might be related, given it's IMHO a similar issue. Still happens with selinux-policy-targeted-3.13.1-102.el7_3.7.noarch and
subscription-manager-1.17.15-1.el7.x86_64:

Adding workaround for now: # cat rhsmcertd_signull.cil (allow rhsmcertd_t kernel_t (process (signull))) # semodule -i rhsmcertd_signull.cil Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
