If you are able to reproduce the issue, then valgrind would be a sure way to debug this since it is memory corruption, but we'd probably need help from NetworkManager developers to figure out how to run it under valgrind. Upstream issue is here: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/1403 This bug appears to have been reported against 'rawhide' during the Fedora Linux 40 development cycle.
