CVE-2026-5067

A remote, unauthenticated attacker can trigger memory corruption in Zephyr's HTTP server WebSocket upgrade path by sending a crafted Sec-WebSocket-Key header. The HTTP/1 header parser copies the header into a fixed-size buffer using a bounded copy that does not guarantee NUL termination when the...

CVE-2026-5067

The CVE targets Zephyr’s HTTP server WebSocket upgrade path (CONFIG_HTTP_SERVER_WEBSOCKET enabled). A crafted Sec-WebSocket-Key header can trigger memory corruption via a non-NUL-terminated copy into a fixed-size buffer, followed by copying to a local stack buffer and using strlen(). If no NUL ex...
