CVE-2026-67301 is a client-side out-of-bounds read in FreeRDP versions before 3.29.0. The flaw affects AsyncUpdate message-proxy handling for PolygonSC and PolygonCB primary drawing orders. In update_message_PolygonSC() and update_message_PolygonCB(), a newly allocated points array is populated from the address of the order structure rather than the corresponding polygon points array. Crafted PolygonSC or PolygonCB orders from an RDP server can therefore cause FreeRDP to read beyond intended memory boundaries.
