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-2021-26341

Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage.

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-2021-26316

Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution.

CVE-2020-12930

Improper parameters handling in AMD Secure Processor (ASP) drivers may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.

CVE-2021-26384

A malformed SMI (System Management Interface) command may allow an attacker to establish a corrupted SMI Trigger Info data structure, potentially leading to out-of-bounds memory reads and writes when triggering an SMI resulting in a potential loss of resources.

CVE-2023-20558

Insufficient control flow management in AmdCpmOemSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to an escalation of privileges.

CVE-2021-26393

Insufficient memory cleanup in the AMD Secure Processor (ASP) Trusted Execution Environment (TEE) may allow an authenticated attacker with privileges to generate a valid signed TA and potentially poison the contents of the process memory with attacker controlled data resulting in a loss of confiden...

CVE-2020-12931

Improper parameters handling in the AMD Secure Processor (ASP) kernel may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity.

CVE-2021-26392

Insufficient verification of missing size check in 'LoadModule' may lead to an out-of-bounds write potentially allowing an attacker with privileges to gain code execution of the OS/kernel by loading a malicious TA.

CVE-2022-23815

Improper bounds checking in APCB firmware may allow an attacker to perform an out of bounds write, corrupting the APCB entry, potentially leading to arbitrary code 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-2021-26367

A malicious attacker in x86 can misconfigure the Trusted Memory Regions (TMRs), which may allow the attacker to set an arbitrary address range for the TMR, potentially leading to a loss of integrity and availability.

CVE-2023-20589

An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially leading to arbitrary code execution.

CVE-2023-20559

Insufficient control flow management in AmdCpmGpioInitSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to escalation of privileges.
