CVE-2023-45935

Medium severity, CVSS 4.2. EPSS: 0.2% chance of exploitation in the next 30 days.

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.
