CVE-2021-26403amd1st gen epyc+42
EPSS score0.12%
Insufficient checks in SEV may lead to a malicious hypervisor disclosing the launch secret potentially resulting in compromise of VM confidentiality.CVE-2021-26331amd1st gen amd epyc™+60EPSS score0.29%
AMD System Management Unit (SMU) contains a potential issue where a malicious user may be able to manipulate mailbox entries leading to arbitrary code execution.CVE-2021-26406amd1st gen amd epyc™ processors+52EPSS score0.42%
Insufficient validation in parsing Owner's
Certificate Authority (OCA) certificates in SEV (AMD Secure Encrypted Virtualization)
and SEV-ES user application can lead to a host crash potentially resulting in
denial of service.CVE-2021-26398amd1st gen epyc+66EPSS score0.21%
Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution.CVE-2021-26342amdepyc_7001_firmware+38EPSS score0.22%
In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of SEV guest memory contents. Users of SEV-ES/SEV-SNP guest VMs are not impacted by this vulnerability.CVE-2021-26311amdepyc_7232p_firmware+65EPSS score1.68%
In the AMD SEV/SEV-ES feature, memory can be rearranged in the guest address space that is not detected by the attestation mechanism which could be used by a malicious hypervisor to potentially lead to arbitrary code execution within the guest VM if a malicious administrator has access to compromise the server hypervisor.CVE-2021-26356amd1st gen amd epyc™ processors+105EPSS score0.40%
A TOCTOU in ASP bootloader may allow an attacker
to tamper with the SPI ROM following data read to memory potentially resulting
in S3 data corruption and information disclosure.CVE-2021-26344amdamd athlon™ 3000 series desktop processors with radeon™ graphics+83EPSS score0.16%
An out of bounds memory write when processing the AMD
PSP1 Configuration Block (APCB) could allow an attacker with access the ability
to modify the BIOS image, and the ability to sign the resulting image, to
potentially modify the APCB block resulting in arbitrary code execution.CVE-2021-26408amd1st gen amd epyc™+39EPSS score0.27%
Insufficient validation of elliptic curve points in SEV-legacy firmware may compromise SEV-legacy guest migration potentially resulting in loss of guest's integrity or confidentiality.CVE-2021-26335amdathlon™ series+59EPSS score0.29%
Improper input and range checking in the AMD Secure Processor (ASP) boot loader image header may allow an attacker to use attacker-controlled values prior to signature validation potentially resulting in arbitrary code execution.CVE-2021-26330amd1st gen amd epyc™+60EPSS score0.22%
AMD System Management Unit (SMU) may experience a heap-based overflow which may result in a loss of resources.CVE-2021-26341amda10-9600p_firmware+125EPSS score0.32%
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage.CVE-2021-26371amd1st gen amd epyc™ processors+140EPSS score0.19%
A compromised or malicious ABL or UApp could
send a SHA256 system call to the bootloader, which may result in exposure of
ASP memory to userspace, potentially leading to information disclosure.CVE-2021-26401amda10-9600p_firmware+216EPSS score0.29%
LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.CVE-2021-26340amdamd epyc™+105EPSS score0.25%
A malicious hypervisor in conjunction with an unprivileged attacker process inside an SEV/SEV-ES guest VM may fail to flush the Translation Lookaside Buffer (TLB) resulting in unexpected behavior inside the virtual machine (VM).CVE-2021-46744amdamd processors+99EPSS 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.
