EPSS score
0.22%
Insufficient checks in System Management Unit (SMU) FeatureConfig may result in reenabling features potentially resulting in denial of resources and/or denial of service.
9.8CVE-2021-26379amd2nd gen amd epyc™+49
EPSS score
0.68%
Insufficient input validation of mailbox data in the SMU may allow an attacker to coerce the SMU to corrupt SMRAM, potentially leading to a loss of integrity and privilege escalation.
5.5CVE-2021-26327amd3rd gen amd epyc™+20
EPSS score
0.24%
Insufficient validation of guest context in the SNP Firmware could lead to a potential loss of guest confidentiality.
5.5CVE-2021-26336amdathlon™ series+96
EPSS score
0.22%
Insufficient bounds checking in System Management Unit (SMU) may cause invalid memory accesses/updates that could result in SMU hang and subsequent failure to service any further requests from other components.
7.8CVE-2021-26331amd1st gen amd epyc™+60
EPSS score
0.29%
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.
7.8CVE-2021-26315amd3rd gen amd epyc™+20
EPSS score
0.17%
When the AMD Platform Security Processor (PSP) boot rom loads, authenticates, and subsequently decrypts an encrypted FW, due to insufficient verification of the integrity of decrypted image, arbitrary code may be executed in the PSP when encrypted firmware images are used.
7.8CVE-2021-26398amd1st gen epyc+66
EPSS score
0.21%
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.
5.5CVE-2021-26339amdathlon™ series+85
EPSS score
0.28%
A bug in AMD CPU’s core logic may allow for an attacker, using specific code from an unprivileged VM, to trigger a CPU core hang resulting in a potential denial of service. AMD believes the specific code includes a specific x86 instruction sequence that would not be generated by compilers.
3.3CVE-2021-26342amdepyc_7001_firmware+38
EPSS score
0.22%
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.
5.5CVE-2021-26354amd2nd gen amd epyc™ processors+169
EPSS score
0.18%
Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to a loss of integrity.
7.8CVE-2021-26324amd3rd gen amd epyc™+23
EPSS score
0.27%
A bug with the SEV-ES TMR may lead to a potential loss of memory integrity for SNP-active VMs.
7.8CVE-2021-26326amd3rd gen amd epyc™+20
EPSS score
0.26%
Failure to validate VM_HSAVE_PA during SNP_INIT may result in a loss of memory integrity.
5.5CVE-2021-26364amdepyc_7232p_firmware+44
EPSS score
0.22%
Insufficient bounds checking in an SMU mailbox register could allow an attacker to potentially read outside of the SRAM address range which could result in an exception handling leading to a potential denial of service.
9CVE-2021-26311amdepyc_7232p_firmware+65
EPSS score
1.68%
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.
7.8CVE-2021-26316amd1st gen epyc+152
EPSS score
0.26%
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.
7.4CVE-2021-26356amd1st gen amd epyc™ processors+105
EPSS score
0.40%
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.
