Description SMASH SMASH 2024-03-28 11:08:26 UTC 
Qt 6 through 6.6 was discovered to contain a NULL pointer dereference via the function QXcbConnection::initializeAllAtoms(). NOTE: this is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server.

Probably relevant for all qt6-base versions.
