    Package        : atop     Version        : 2.6.0-2+deb11u1     CVE ID         : CVE-2025-31160

    It was discovered that Atop, a monitor tool for system resources and     process activity, always tried to connect to the port of atopgpud     (an additional daemon gathering GPU statistics not shipped in Debian)     while performing insufficient sanitising of the data read from this     port.

    With this update, additional validation is added and by default atop     no longer tries to connect to the atopgpud daemon port unless explicitly     enabled via -k.

    For Debian 11 bullseye, this problem has been fixed in version     2.6.0-2+deb11u1.

    We recommend that you upgrade your atop packages.
