的高危硬件漏洞，該漏洞波及 AMD 自 2017 年 Zen 1 至 2024 年 Zen 5 的全系處理器。IT之家援引博文介紹，StackWarp 利用了堆棧引擎（一項性能優化功能）中的同步故障，操控一個未公開的模型特定寄存器（MSR 0xC0011029）控制位，該控制位用於啓用或禁用堆棧指針跟蹤。惡意的雲提供商可以通過 CPU 線程切換該控制位，引發連鎖反應，影響運行加密虛擬機的同級線程。這種操作會讓 CPU 「凍結」堆棧指針的架構更新。在攻擊者重新啓用引擎後，累積的偏移量會瞬間「釋放」，導致堆棧指針發生高達 640 字節的確定性位移。值得注意的是，這種攻擊無需訪問訪客明文或注入中斷，完全避開了傳統安全監控。研究人員通過演示證實了 StackWarp 的破壞力。在加密操作過程中，攻擊者僅需通過精準的堆棧操控破壞一個簽名，即可提取出 RSA-2048 私鑰。此外，攻擊者還能利用該漏洞將堆棧移動 32 個字節，直接跳過 OpenSSH 的密碼驗證環節，或者通過破壞系統調用的返回值，將普通用户權限提升至 Root 級。這意味着，原本被企業視為「數據保險箱」的機密計算環境，可能已淪為攻擊者的後花園。AMD 目前已確認該漏洞，並分配了 CVE-2025-29943 編號，同時向企業客户發布了微碼補丁。然而，在硬件級修復方案隨下一代處理器問世前，現有的臨時解決方案代價高昂。為了徹底阻斷攻擊路徑，用户需要禁用同步多線程（SMT / 超線程）技術。這一操作雖然有效，但會直接導致可用 CPU 核心數減半，迫使企業在保障數據安全與維持計算性能之間做出痛苦的抉擇。IT之家附上參考地址","kind":"news","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"-2","news_tag":"policyRegulatory","news_rank":0,"symbols":[],"gpt_button":0,"need_auth":false,"code":"91000000","status":"200"}}}
