Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure. Los alias en el predictor de bifurcación pueden causar que algunos procesadores AMD predigan el tipo de bifurcación incorrecto, conllevando a una divulgación de información A flaw was found in hw.

CVSS: 6.5EPSS: 0%CPEs: 288EXPL: 0CVE-2022-29901 – Arbitrary Memory Disclosure through CPU Side-Channel Attacks (Retbleed)
https://notcve.org/view.php?id=CVE-2022-29901
Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions. Las generaciones de microprocesadores Intel 6 a 8 están afectadas por una nueva variante de Spectre que es capaz de omitir su mitigación de retpoline en el kernel para filtrar datos arbitrarios. Un atacante con acceso de usuario no privilegiado puede secuestrar las instrucciones de retorno para lograr una ejecución arbitraria de código especulativo bajo determinadas condiciones dependientes de la microarquitectura A flaw was found in hw. Non-transparent sharing of branch predictor targets between contexts in some Intel(R) processors may potentially allow an authorized user to enable information disclosure via local access. • http://www.openwall.com/lists/oss-security/2022/07/12/2 http://www.openwall.com/lists/oss-security/2022/07/12/4 http://www.openwall.com/lists/oss-security/2022/07/12/5 http://www.openwall.com/lists/oss-security/2022/07/13/1 https://comsec.ethz.ch/retbleed https://lists.debian.org/debian-lts-announce/2022/09/msg00011.html https://lists.debian.org/debian-lts-announce/2022/12/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fed • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-668: Exposure of Resource to Wrong Sphere •
