cyberkendra 昨日（7 月 9 日）发布博文，报道称微软联合苏黎世联邦理工学院的研究人员，在主流 AMD 和英特尔处理器中，发现了 4 种新型推测执行侧通道漏洞，可以绕过现有的微架构防御措施。在题为“Enter, Exit, Page Fault, Leak”的论文中，研究团队创新引入了基于模型的关联测试（Model-Based Relational Testing，MRT）方法，通过压力测试安全域边界来评估安全性。团队定制了相关测试框架，在 AMD Zen 3 和 Zen 4 芯片上发现了新的泄漏向量，并证实了熔断（Meltdown）和微架构数据采样（MDS）等几个已知漏洞。研究人员将他们的方法描述为从“反应性修复”转向“处理器设计中的主动安全验证”，为 CPU 安全评估指明了新方向。IT之家援引博文内容，简要介绍下研究团队发现的 4 个漏洞：上述四个漏洞被 AMD 统称为瞬态调度攻击（TSA），并分别编录为 CVE-2024-36350 和 CVE-2024-36357。根据 AMD 的白皮书，这些攻击源于“错误完成”—— 推测事件中无效数据影响执行时间而不触发管道刷新，导致基于时间的数据泄露。问题的核心在于现代 CPU 如何处理不同安全域（如虚拟机和宿主机）之间的推测执行。现有的缓解措施，如刷新缓冲区和页面隔离，目前无法完全解决这些漏洞。AMD 已经发布了更新的微代码，并建议在受信任和不受信任的上下文之间转换时使用 VERW 指令来清除易受攻击的微架构状态。然而，这可能会影响性能，并且必须在操作系统和虚拟机监控程序代码库中实施。研究人员强调，在架构隔离（安全域的正式分离）和微架构行为（如推测执行和共享缓存）的实际现实之间存在持续的差距。云服务提供商、虚拟化平台和操作系统供应商必须注意这一点。即使有微代码修复，完全缓解也需要软件层面的合作。（转自：网易科技）\n\n\n海量资讯、精准解读，尽在新浪财经APP","kind":"news","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"-1","news_tag":"","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":1,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0
