CVE-2022-29900
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.
CVE-2022-23825
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.
CVE-2022-23824
IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure.
CVE-2022-27672
When SMT is enabled, certain AMD processors may speculatively execute instructions using a targetfrom the sibling thread after an SMT mode switch potentially resulting in information disclosure.
CVE-2022-23823
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.
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.
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.
CVE-2023-20579
ImproperAccess Control in the AMD SPI protection feature may allow a user with Ring0(kernel mode) privileged access to bypass protections potentially resulting inloss of integrity and availability.
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 inform...
CVE-2022-23820
Failure to validate the AMD SMM communication buffermay allow an attacker to corrupt the SMRAM potentially leading to arbitrarycode execution.
CVE-2023-20555
Insufficient input validation inCpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwritingan arbitrary bit in an attacker-controlled pointer potentially leading toarbitrary code execution in SMM.
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.
