https://notcve.org/view.php?id=CVE-2023-20588
08 Aug 2023 — A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. Un error de división por cero en algunos procesadores AMD puede potencialmente devolver datos especulativos que resulten en una pérdida de confidencialidad. It was discovered that the ASUS HID driver in the Linux kernel did not properly handle device removal, leading to a use-after-free vulnerability. A local attacker with physical access could plug in a specially crafted USB device ... • http://www.openwall.com/lists/oss-security/2023/09/25/3 • CWE-369: Divide By Zero •

https://notcve.org/view.php?id=CVE-2020-12965
04 Feb 2022 — When combined with specific software sequences, AMD CPUs may transiently execute non-canonical loads and store using only the lower 48 address bits potentially resulting in data leakage. Cuando se combinan con secuencias de software específicas, las CPUs de AMD pueden ejecutar transitoriamente cargas no canónicas y almacenar usando sólo los 48 bits de dirección inferiores, resultando potencialmente en un filtrado de datos • http://www.openwall.com/lists/oss-security/2023/12/05/3 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
