CVE-2026-78408: Missing Release of File Descriptor or Handle after Effective Lifetime in Red Hat Red Hat Enterprise Linux 10CVE-2026-78408 0 The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve(). Because the kernel checks later cgroup migrations using the credentials from the original open, a program run in an attacker-controlled target can inherit root's ability to move host processes between cgroups. After a privileged operator uses --join-cgroup against that target, an unprivileged user can migrate and terminate unrelated root processes.
