| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2023-4969 | A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures. | [email protected] | 6.5 | 1.18% | 2024-01-16 | 2026-06-17 |
| CVE-2022-23821 | Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution. | [email protected] | 9.8 | 0.99% | 2023-11-14 | 2026-06-17 |
| CVE-2022-23820 | Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution. | [email protected] | 7.5 | 0.70% | 2023-11-14 | 2026-06-17 |
| CVE-2021-46758 | Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of availability and integrity. | [email protected] | 6.1 | 0.33% | 2023-11-14 | 2026-06-17 |
| CVE-2023-20555 | Insufficient input validation in CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting an arbitrary bit in an attacker-controlled pointer potentially leading to arbitrary code execution in SMM. | [email protected] | 7.8 | 0.30% | 2023-08-08 | 2026-06-17 |
| CVE-2021-46778 | Execution unit scheduler contention may lead to a side channel vulnerability found on AMD CPU microarchitectures codenamed “Zen 1”, “Zen 2” and “Zen 3” that use simultaneous multithreading (SMT). By measuring the contention level on scheduler queues an attacker may potentially leak sensitive information. | [email protected] | 5.6 | 0.22% | 2022-08-10 | 2026-06-17 |
| CVE-2021-26401 | LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs. | [email protected] | 5.6 | 0.28% | 2022-03-11 | 2026-06-16 |
| CVE-2021-26341 | Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage. | [email protected] | 6.5 | 0.31% | 2022-03-11 | 2026-06-16 |
