As you may be aware, a potential vulnerability has been identified that may cause a “GPS Week Number Roll-over” type event to occur within systems utilizing Network Timing Protocol Daemon (NTPD) and GPS Daemon (GPSD) software. On October 24th 2021, A bug in older versions of the software may trigger the system date to roll back to sometime in March 2002. All systems running the most recent software update, version 3.23.1 (released September 21, 2021) should be unaffected.
While this is not a problem with GPS, this has the potential to cause significant impact.
