CWE ID 787


CVE-2023-48229 is a vulnerability in the Contiki-NG operating system for Next-Generation IoT devices. The vulnerability exists in the driver for IEEE 802.15.4 radios on nRF platforms, specifically in the `read_frame` function in the `arch/cpu/nrf/net/nrf-ieee-driver-arch.c` module. It is triggered when parsing radio frames and occurs due to incomplete validation of the payload length of the packet. This allows an external party to set a value that exceeds the buffer size, leading to an out-of-bounds write. The vulnerability has been patched in the "develop" branch of Contiki-NG and users are advised to update to this branch or a subsequent release. Failure to do so could result in potential exploitation, with a base severity rating of HIGH, impacting availability.
