      What were you trying to do that didn't work?

      The following automated test triggers SELinux denials:

      • /CoreOS/selinux-policy/Sanity/thumbnail-protection

      Please provide the package NVR for which bug is seen:

      selinux-policy-38.1.31-1.el9.noarch
      selinux-policy-devel-38.1.31-1.el9.noarch
      selinux-policy-targeted-38.1.31-1.el9.noarch
      tumbler-4.18.1-1.el9.x86_64

      How reproducible:

      always

      Steps to reproduce

      1. get a RHEL-9.4 machine (the targeted policy is active)
      2. run the automated test
      3. search for SELinux denials

      Expected results

      no SELinux denials

      Actual results
