Key Findings Researchers have disclosed a new hardware vulnerability, codenamed "StackWarp", affecting AMD Zen 1 through Zen 5 processors. The flaw can be exploited to bypass AMD's Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP) protections, allowing attackers to run malicious code within confidential virtual machines (CVMs). StackWarp targets a synchronization bug in the CPU's stack engine, a microarchitectural optimization responsible for accelerated sta
