CVE-2021-26354

Insufficient bounds checking in ASP may allow anattacker to issue a system call from a compromised ABL which may causearbitrary memory values to be initialized to zero, potentially leading to aloss of integrity.

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 inform...
