CVE-2025-31160 Atop 2.11 heap problems:

"atop always tries to connect
to the TCP port of 'atopgpud' during initialization. When another local
program has been started (instead of 'atopgpud') that listens to this TCP
port, atop connects to that program. Such program is able then to send
unexpected strings that may lead to parsing failures in atop. These failures
result in heap problems and segmentation faults."
