This issue might allow attackers to run harmful code in rare configurations without modern protections. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 8; Red Hat Hardened Images; Red Hat Enterprise Linux 9; and 2 more. Affected products named by the advisory: Red Hat JBoss Core Services; Red Hat OpenShift Container Platform 4.
