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. • http://www.openwall.com/lists/oss-security/2022/11/10/2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NTQMPJC5N6XJYQ232OZFLK47HVZNRBY3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YTMITQBGC23MSDHUCAPCVGLMVXIBXQTQ https://security.gentoo.org/glsa/202402-07 https://www.amd.com/en/corporate/product-security/bulletin/amd-sb-1040 https://www.debian.org/security/2023/dsa-5378 •
