CVE-2021-46744amdamd processors+99
EPSS score0.33%
An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV guest on AMD CPUs by monitoring ciphertext values over time.CVE-2021-46756amd1st gen amd epyc™ processors+80EPSS score0.65%
Insufficient validation of inputs in
SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an
attacker with a malicious Uapp or ABL to send malformed or invalid syscall to
the bootloader resulting in a potential denial of service and loss of
integrity.CVE-2021-46774amd1st gen amd epyc™ processors+149EPSS score0.51%
Insufficient DRAM address validation in System
Management Unit (SMU) may allow an attacker to read/write from/to an invalid
DRAM address, potentially resulting in denial-of-service.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-2020-12951amdathlon™ series+59EPSS score0.22%
Race condition in ASP firmware could allow less privileged x86 code to perform ASP SMM (System Management Mode) operations.CVE-2020-12944amdathlon™ series+58EPSS score0.35%
Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution.CVE-2020-12966amd1st/2nd/3rd gen amd epyc™ processors+107EPSS score0.31%
AMD EPYC™ Processors contain an information disclosure vulnerability in the Secure Encrypted Virtualization with Encrypted State (SEV-ES) and Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). A local authenticated attacker could potentially exploit this vulnerability leading to leaking guest data by the malicious hypervisor.CVE-2020-12954amd1st gen amd epyc™+60EPSS score0.23%
A side effect of an integrated chipset option may be able to be used by an attacker to bypass SPI ROM protections, allowing unauthorized SPI ROM modification.CVE-2020-12967amdepyc_7232p_firmware+65EPSS score1.68%
The lack of nested page table protection in the AMD SEV/SEV-ES feature could potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor.CVE-2020-12988amd1st/2nd/3rd gen amd epyc™ processors+61EPSS score1.04%
A potential denial of service (DoS) vulnerability exists in the integrated chipset that may allow a malicious attacker to hang the system when it is rebooted.CVE-2022-29900amda10-9600p_firmware+214EPSS score3.94%
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.CVE-2022-23823amda10-9600p_firmware+142EPSS score1.17%
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.CVE-2022-23824amda10-9600p_firmware+205EPSS score0.60%
IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure.CVE-2022-23825amda10-9600p_firmware+255EPSS score0.78%
Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.CVE-2023-20588amdathlon_gold_3150g_firmware+159EPSS score11.15%
A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality.CVE-2023-20592amd1st gen amd epyc™ processors+91EPSS score1.02%
Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity.CVE-2023-20527amd1st gen epyc+66EPSS score0.60%
Improper syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory out-of-bounds, potentially leading to a denial-of-service.CVE-2023-20521amd1st gen amd epyc™ processors+106EPSS score0.26%
TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service.CVE-2023-20520amd1st gen amd epyc™+65EPSS score0.79%
Improper access control settings in ASP
Bootloader may allow an attacker to corrupt the return address causing a
stack-based buffer overrun potentially leading to arbitrary code execution.CVE-2023-20578amdepyc_7001_firmware+104EPSS score0.12%
A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow
an attacker with ring0 privileges and access to the
BIOS menu or UEFI shell to modify the communications buffer potentially
resulting in arbitrary code execution.
