How to fix?

Upgrade Echo:latest qtbase-opensource-src to version 5.15.8+dfsg-11+deb12u3+e1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream qtbase-opensource-src package and not the qtbase-opensource-src package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

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.
