CVE-2023-20569 – amd: Return Address Predictor vulnerability leading to information disclosure
https://notcve.org/view.php?id=CVE-2023-20569
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure. Una vulnerabilidad de canal lateral en algunas de las CPU de AMD puede permitir que un atacante influya en la predicción de la dirección de retorno. Esto puede dar lugar a una ejecución especulativa en una dirección controlada por el atacante, lo que podría conducir a la divulgación de información. A side channel vulnerability was found in hw amd. • http://www.openwall.com/lists/oss-security/2023/08/08/4 http://xenbits.xen.org/xsa/advisory-434.html https://comsec.ethz.ch/research/microarch/inception https://lists.debian.org/debian-lts-announce/2023/08/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/HKKYIK2EASDNUV4I7EFJKNBVO3KCKGRR https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/L4E4TZNMLYL2KETY23IPA43QXFAVJ46V https://lists.fedoraproject.org/archives/list/pack • CWE-203: Observable Discrepancy •
