    Debian Bug     : 1087917 1087918 1087957 1087958 1088012 1088047

    The update for needrestart announced as DSA 5815-1 introduced a
    regression reporting false positives for processes running in chroot or
    mountns. Updated packages are now available to correct this issue.

    For the stable distribution (bookworm), this problem has been fixed in
    version 3.6-4+deb12u3.

    We recommend that you upgrade your needrestart packages.

    For the detailed security status of needrestart please refer to its
    security tracker page at:
    https://security-tracker.debian.org/tracker/needrestart
