The vulnerability arises from a race condition during process termination, enabling a brief window where sensitive data, such as SSH host private keys or /etc/shadow contents, can be disclosed. This could lead to unauthorized access to sensitive information on affected Red Hat Enterprise Linux systems.\n\nIn OpenShift Container Platform 4, this flaw is rated Low. The default `restricted-v2` Security Context Constraint (SCC) sets `allowPrivilegeEscalation: false` on all pods, which causes the kernel to ignore setuid file bits and prevents target binaries from opening privileged files, breaking the exploit chain entirely. Under non-default SCCs such as `anyuid` that permit privilege escalation, the vulnerability is constrained by PID and mount namespace isolation to the container's own filesystem. An attacker would only be able to access root-owned files already within the container, not host or cross-pod resources. In practice, containers rarely contain sensitive root-owned files that are not already accessible to the pod user through normal means.",
