CVE-2026-13479

The LoRaWAN application-layer clock-synchronization service parses downlinks in clocksyncpackagecallback subsys/lorawan/services/clocksync.c. Its command loop only guarantees that the one-byte command id is in bounds; for the CLOCKSYNCCMDAPPTIME AppTimeAns command the handler then reads a 4-byte...

CVE-2026-13479

Zephyr RTOS LoRaWAN clock-synchronization service (subsys/lorawan/services/clock_sync.c) contains an out-of-bounds read in clock_sync_package_callback(). When processing the CLOCK_SYNC_CMD_APP_TIME (AppTimeAns) downlink, the handler reads a 4-byte time correction and a 1-byte token without verify...

Time not getting sync on XenServer with NTP

High NTP offset and jitter while delay is low. This can be seen with "ntpq -p". Offset is the time difference between the local server and remote Jitter is the difference between the last and current offset measurements, thus if it is high, it means that the offset is increasing more over time...

Denial of service vulnerability in ntpd

Network Time Protocol NTP is a protocol used to synchronize a computer's time to its server or clock source e.g., quartz clock, GPS, etc.. Synchronizing a computer's clock to UTC ensures that data interactions in a network can proceed smoothly.NTPD Network Time Protocol daemon is an operating...

RHEL 4 : ntp (RHSA-2006:0393)

Updated ntp packages that fix several bugs are now available. This update has been rated as having low security impact by the Red Hat Security Response Team. The Network Time Protocol NTP is used to synchronize a computer's time with a reference time source. The NTP daemon ntpd, when run with the...
