CVE-2026-26453

Beschreibung

ccoap 77f55c4b466e99327c24ace8a2913d3ba7e2ccd5 contains a null pointer dereference vulnerability in the coap_server_handle_session() function when processing COAP messages containing URI_PATH options with NULL data pointers. When the server searches for a URI_PATH option matching the string -separate-, it directly calls strncmp() on option_list[i].data without checking if the pointer is NULL. This causes a segmentation fault when the option-s data field is NULL.
