GhostRace: Exploiting and Mitigating Speculative Race Conditions
Race conditions arise when multiple threads attempt to ac- cess a shared resource without proper synchronization, often leading to vulnerabilities such as concurrent use-after-free. To mitigate their occurrence, operating systems rely on syn- chronization primitives such as mutexes, spinlocks, etc. In this paper, we present…
