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 •
