CVE-2021-26341amda10-9600p_firmware+125
EPSS score0.32%
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage.CVE-2021-26401amda10-9600p_firmware+216EPSS score0.29%
LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.CVE-2021-46758amdamd ryzen™ 5000 series processors with radeon™ graphics “barcelo”+69EPSS score0.33%
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.CVE-2021-46778amdamd processors+179EPSS score0.23%
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.CVE-2022-23821amdamd ryzen™ embedded 5000+131EPSS score0.99%
Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.CVE-2022-23820amd3rd gen amd epyc™ processors+123EPSS score0.70%
Failure to validate the AMD SMM communication buffer
may allow an attacker to corrupt the SMRAM potentially leading to arbitrary
code execution.CVE-2023-20555amdathlon_3015ce_firmware+133EPSS score0.32%
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.CVE-2023-4969amdathlon_3000g_firmware+135EPSS score1.19%
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.
