Fix global buffer overflow in test_kpgen_certwrite of pkcs11-tool. The length returned by getID() was not validated before memcpy into the fixed-size 100-byte opt_object_id buffer, allowing a global buffer overflow when a malicious PKCS#11 module or smart card returns an oversized CKA_ID.

CVE 修复
CVE ID: CVE-2026-10275
漏洞描述: OpenSC pkcs11-tool 中的 test_kpgen_certwrite 函数在处理 PKCS#11 模块或智能卡返回的 CKA_ID 属性时，未进行边界检查即将数据复制到固定的 100 字节全局缓冲区 opt_object_id，导致全局缓冲区溢出。
修复方案: 在 memcpy 前添加长度校验，如果返回的 CKA_ID 长度超过目标缓冲区大小（100字节），则报错退出。
受影响版本: OpenSC <= 0.26.1
当前版本: 0.25.1-1deepin5
验证状态: patch 已验证
