The golioth_payload_as_int() and golioth_payload_as_float() helpers copy network-supplied payload data into fixed-size stack buffers using memcpy() with a length derived from payload_size. The only length checks are guarded by assert(); in release builds, the asserts are compiled out and memcpy() may copy an unbounded payload_size. Payloads larger than 12 bytes (int) or 32 bytes (float) can overflow the stack, resulting in a crash\/denial of service. This is reachable via LightDB State on_payload with a malicious server or MITM.<\/p>\n<p>Severity: 3.7 | LOW<\/p>\n<p>Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID : CVE-2026-23747 Published : Feb. 26, 2026, 6:23 p.m. | 47\u00a0minutes ago Description : Golioth Firmware SDK version 0.10.0 prior to 0.22.0, fixed in commit\u00a048f521b, contain a stack-based buffer overflow in Payload Utils.
