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-2021-26390
A malicious or compromised UApp or ABL may coerce the bootloader into corrupting arbitrary memory potentially leading to loss of integrity of data.
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-2021-26393
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-2021-26346
Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service.

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-2021-26354
Insufficient bounds checking in ASP may allow anattacker to issue a system call from a compromised ABL which may causearbitrary memory values to be initialized to zero, potentially leading to aloss of integrity.
CVE-2021-26371
A compromised or malicious ABL or UApp couldsend a SHA256 system call to the bootloader, which may result in exposure ofASP memory to userspace, potentially leading to information disclosure.
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-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...
