CVE-2026-111733：P-Net 1.0.3 之前版本 NULL 指標解引用漏洞
CVE-2026-111733 - NULL pointer dereference on implicit read of AR specific record index
summary_zh: 遠端未授權攻擊者可向 P-Net 1.0.3 之前版本傳送缺少有效 AR UUID 的隱式讀取請求，導致 NULL 指標解引用並造成裝置崩潰（拒絕服務）。
P-Net before 1.0.3 dereferences a NULL AR pointer when handling an implicit read request without a valid target AR UUID for a record index that requires an AR (AR specific indices 0xE000-0xEFFF, and the expected identification data of a slot or subslot). A remote unauthenticated attacker can send such a request to crash the device (denial of service).
