CVE-2026-13480 Out-of-bounds read in LoRaWAN fragmented data block transport (FUOTA) downlink handler

The LoRaWAN TS004 Fragmented Data Block Transport handler fragtransportpackagecallback in subsys/lorawan/services/fragtransport.c parses downlink command bytes without validating that enough payload bytes remain before each access. The loop's only bound is rxpos fragsize, capped at...

CVE-2026-13480

CVE-2026-13480 is an out-of-bounds read in the Zephyr RTOS LoRaWAN TS004 Fragmented Data Block Transport (FUOTA) downlink handler (frag_transport_package_callback() in subsys/lorawan/services/frag_transport.c). The handler fails to validate remaining payload length before casting to a 10-byte set...

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...

CVE-2026-13479 Out-of-bounds read in LoRaWAN clock-sync AppTimeAns downlink handler

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...
