CVE-2026-87045

A NULL pointer dereference exists in the Zephyr HTTP/2 server within subsys/net/lib/http/http_server_http2.c. The vulnerability occurs because handle_http_frame_header() unconditionally sets client->current_stream = NULL, but CONTINUATION frames do not re-bind the stream. This leads to a NULL ...
