Researchers Uncover First Native Spectre v2 Exploit Against Linux Kernel

Cybersecurity researchers have disclosed what they say is the "first native Spectre v2 exploit" against the Linux kernel on Intel systems that could be exploited to read sensitive data from the memory. The exploit, called Native Branch History Injection (BHI), can be used to leak arbitrary kernel memory at 3.5 kB/sec by bypassing existing Spectre v2/BHI mitigations, researchers from Systems and

GhostRace – New Data Leak Vulnerability Affects Modern CPUs

A group of researchers has discovered a new data leakage attack impacting modern CPU architectures supporting speculative execution. Dubbed GhostRace (CVE-2024-2193), it is a variation of the transient execution CPU vulnerability known as Spectre v1 (CVE-2017-5753). The approach combines speculative execution and race conditions. "All the common synchronization primitives implemented
