09 Nov 2022 — IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. IBPB no puede evitar que las predicciones de sucursales de retorno sean especificadas por objetivos de sucursales anteriores a IBPB, lo que lleva a una posible divulgación de información. Multiple vulnerabilities have been found in Xen, the worst of which can lead to arbitrary code execution. Versions greater than or equal to 4.16.6_pre1 are affected. • http://www.openwall.com/lists/oss-security/2022/11/10/2 •

09 Aug 2022 — 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 information.
