苏黎世联邦理工学院研究人员发现英特尔处理器新漏洞ETH Zurich Researchers Discover New Security Flaw in Intel Processors
➀ 苏黎世联邦理工学院研究人员在英特尔处理器中发现了一类新型漏洞(BPRC),利用预测执行技术突破CPU用户间的权限屏障,非法获取缓存和内存数据;
➁ 该漏洞影响2018年后的所有英特尔处理器,对共享硬件资源的云环境构成严重威胁,攻击者可每秒读取高达5000字节的其他用户内存数据;
➂ 英特尔已通过微代码更新修复漏洞,但此发现揭示了预测技术架构存在的根本性设计缺陷,需持续修补以应对未来潜在风险。
➀ ETH Zurich researchers identified a new class of vulnerabilities (BPRC) in Intel processors, exploiting speculative execution to breach privilege barriers between CPU users and access cached/RAM data;
➁ The flaw affects all Intel processors since 2018, particularly threatening cloud environments where hardware resources are shared, enabling attackers to read up to 5,000 bytes per second of others' memory;
➂ Intel has implemented mitigations via microcode updates, but the discovery highlights fundamental architectural risks in speculative technologies requiring ongoing security patches.
