I'm using Plasma 5.27.3 on Wayland in a Fedora 38 KDE Plasma installation. I started ksysguard from ksysguard-5.22.0-8.fc38.x86_64. A crash notification appeared. gnome-abrt and coredumpctl showed that ksysguardd crashed repeatedly after starting ksysguard when lmSensors was being initalized. The function __GI___fortify_fail showed the error "buffer overflow detected" in frame 5 of the trace which was like that in this report.
Core was generated by `/usr/bin/ksysguardd'.
Program terminated with signal SIGABRT, Aborted.

The crash happened 264 times according to coredumpctl. Fedora 38 involved a change to use the build flag _FORTIFY_SOURCE=3 https://fedoraproject.org/wiki/Changes/Add_FORTIFY_SOURCE%3D3_to_distribution_build_flags That change might be involved in the buffer overflow being detected. I reported this problem at https://bugs.kde.org/show_bug.cgi?id=467821
This problem might be fixed by the commit lmsensors: Fix buffer size passed to snprintf at https://invent.kde.org/plasma/ksysguard/-/commit/cb52be2f743a6717355445889dd3e2e265ad75fa FEDORA-2023-dd5fbef73f has been submitted as an update to Fedora 38. https://bodhi.fedoraproject.org/updates/FEDORA-2023-dd5fbef73f @matt.fagnani perhaps you could test the update I submitted? If it solves the issue I Will backport it to previous releases. With the update, ksysguardd no longer aborts. Thanks! FEDORA-2023-0fbf82a6f4 has been submitted as an update to Fedora 37. https://bodhi.fedoraproject.org/updates/FEDORA-2023-0fbf82a6f4 ksysguardd didn't crash after I updated to ksysguardd-5.22.0-9.fc38. Thanks. FEDORA-2023-0fbf82a6f4 has been pushed to the Fedora 37 testing repository. Soon you'll be able to install the update with the following command: `sudo dnf upgrade --enablerepo=updates-testing --refresh --advisory=FEDORA-2023-0fbf82a6f4` You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2023-0fbf82a6f4 See also https://fedoraproject.org/wiki/QA:Updates_Testing for more information on how to test updates.
