Solution

No solution given by the vendor.

Workaround

Disable the `pam_namespace` module if it is not essential for your environment, or carefully review and configure it to avoid operating on any directories or paths that can be influenced or controlled by unprivileged users, such as user home directories or world-writable locations like `/tmp`.
