CVE-2026-14368

The LwM2M JSON content formatter's getstring in subsys/net/lib/lwm2m/lwm2mrwjson.c copies a parsed JSON string into a caller-supplied buffer and NUL-terminates it. The length guard used if stringlength buflen, which accepts a string whose length is exactly buflen. After memcpy fills the whole...

CVE-2026-14368

CVE-2026-14368 is an off-by-one out-of-bounds write in the Zephyr RTOS LwM2M JSON content formatter. The get_string() function in subsys/net/lib/lwm2m/lwm2m_rw_json.c uses a boundary check of string_length > buflen instead of >=, allowing a parsed JSON string whose length exactly equals the...

CVE-2026-5855

Contiki-NG's LwM2M TLV parser lwm2mtlvread in os/services/lwm2m/lwm2m-tlv.c ignores its caller-supplied buffer length argument and reads up to six bytes from the input buffer with no bounds check. The caller in lwm2m-engine.c iterates while there is at least one byte remaining, so a crafted CoAP...

CVE-2026-10672

CVE-2026-10672 affects Zephyr LwM2M firmware Update pull: a memcpy(context.uri, uri, LWM2M_PACKAGE_URI_LEN) into a 128-byte buffer, with no length validation, copies up to 128 bytes of a server URI and omits the NUL terminator. Subsequent strlen and CoAP/PROXY_URI parsing read past the end into a...
