CVE-2021-46778
CVE-2021-46778 describes an information-disclosure side-channel vulnerability in AMD CPUs with SMT (Zen 1–Zen 4). The root cause is execution unit scheduler contention on SMT-enabled cores, allowing an attacker to infer data by measuring scheduler-queue contention. Public documents identify affec...
CVE-2021-46778
A contention-based side channel vulnerability was found in hw. Some AMD CPUs using simultaneous multithreading SMT may allow an attacker to measure the contention level on scheduler queues, leading to potential leakage of sensitive information...
CVE-2021-46778
Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading SMT. By measuring the contention level on scheduler queues an attacker may potentially leak sensitive...
