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 •
