Core Viewpoint - The article highlights the emergence of the StackWarp vulnerability affecting multiple AMD ZEN architecture processors, emphasizing the ongoing security risks within the X86 ecosystem. It contrasts this with the immunity demonstrated by domestic CPU manufacturer Haiguang, which has been confirmed to be unaffected by this vulnerability [1][3]. Group 1: Vulnerability Overview - The StackWarp vulnerability, discovered by Germany's CISPA Helmholtz Center for Information Security, allows malicious VM hosts to manipulate the stack pointer of customer virtual machines, enabling remote code execution and privilege escalation within confidential virtual machines [3]. - AMD's SEV-SNP is identified as a critical entry point for this vulnerability, where attackers can alter the RSP register to control execution flow and data within the virtual machine [3][4]. - AMD has acknowledged the vulnerability and stated that low-risk patches have been available for EPYC products since July of the previous year [3]. Group 2: Haiguang's Immunity - Haiguang's CPU, which holds complete X86 licensing, has been noted for its natural immunity to the StackWarp vulnerability due to its proprietary CSV virtualization technology, which fundamentally differs from AMD's SEV-SNP [3][4]. - The article emphasizes that Haiguang's CSV3 technology has effectively closed the attack vectors that StackWarp exploits, showcasing the importance of domestic innovation in CPU security [4]. Group 3: Domestic Innovation and Security - The article discusses the significance of genuine innovation versus mere imitation in the context of domestic chip development, particularly for Haiguang's X86 localization efforts [6]. - Haiguang has independently completed multiple product iterations and established a sustainable C86 technology roadmap, which has led to enhanced performance and security features [6][7]. - The C86 architecture has been designed to inherently support security algorithms and has shown resilience against various vulnerabilities that affect other X86 chips, thereby validating the value of domestic technological self-reliance [7].
