Researchers from IBM and VU Amsterdam have identified a new cybersecurity threat named 'GhostRace' (CVE-2024-2193), a variant of the Spectre v1 vulnerability that affects CPUs with speculative execution. This vulnerability allows attackers to exploit race conditions to leak sensitive data. The discovery highlights its potential impact across all major CPU architectures and operating systems. The threat underscores the ongoing challenges in protecting against speculative execution attacks, which have been a focal point in cybersecurity since the initial discovery of Spectre and Meltdown vulnerabilities.
