6.1CVE-2021-46758amdamd ryzen™ 5000 series processors with radeon™ graphics “barcelo”+69
EPSS score
0.33%
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.
5.6CVE-2021-46778amdamd processors+179
EPSS score
0.23%
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.
6.5CVE-2022-29900amda10-9600p_firmware+214
EPSS score
3.94%
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.
4.7CVE-2022-27672amd1st gen amd epyc™ processors+274
EPSS score
0.28%
When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure.
6.5CVE-2022-23823amda10-9600p_firmware+142
EPSS score
1.17%
A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure.
5.5CVE-2022-23824amda10-9600p_firmware+205
EPSS score
0.60%
IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure.
6.5CVE-2022-23825amda10-9600p_firmware+255
EPSS score
0.78%
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.
9.8CVE-2022-23821amdamd ryzen™ embedded 5000+131
EPSS score
0.99%
Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.
9.8CVE-2022-23820amd3rd gen amd epyc™ processors+123
EPSS score
0.70%
Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.
6CVE-2023-20579amdamd ryzen™ 3000 series processors with radeon™ graphics+142
EPSS score
0.16%
Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and availability.
7.8CVE-2023-20555amdathlon_3015ce_firmware+133
EPSS score
0.32%
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.
6.5CVE-2023-4969amdathlon_3000g_firmware+135
EPSS score
1.19%
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.
5.3CVE-2023-44216amdryzen_5_7600x+28
EPSS score
1.72%
PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.
