CVE-2021-26356 1 Amd 196 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 193 more 2024-11-21 7.4 High
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-2021-26342 1 Amd 76 Epyc 7001, Epyc 7001 Firmware, Epyc 7251 and 73 more 2024-11-21 3.3 Low
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-2021-26341 2 Amd, Redhat 255 A10-9600p, A10-9600p Firmware, A10-9630p and 252 more 2024-11-21 6.5 Medium
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage.
CVE-2021-26340 1 Amd 210 Epyc 7001, Epyc 7001 Firmware, Epyc 7232p and 207 more 2024-11-21 8.4 High
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-2021-26329 1 Amd 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more 2024-11-21 5.5 Medium
AMD System Management Unit (SMU) may experience an integer overflow when an invalid length is provided which may result in a potential loss of resources.
CVE-2021-26322 1 Amd 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more 2024-11-21 7.5 High
Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”.
CVE-2021-26321 1 Amd 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more 2024-11-21 5.5 Medium
Insufficient ID command validation in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP.
CVE-2021-26320 1 Amd 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more 2024-11-21 5.5 Medium
Insufficient validation of the AMD SEV Signing Key (ASK) in the SEND_START command in the SEV Firmware may allow a local authenticated attacker to perform a denial of service of the PSP
CVE-2021-26312 1 Amd 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more 2024-11-21 5.5 Medium
Failure to flush the Translation Lookaside Buffer (TLB) of the I/O memory management unit (IOMMU) may lead an IO device to write to memory it should not be able to access, resulting in a potential loss of integrity.
CVE-2021-26311 1 Amd 65 Epyc 7232p, Epyc 7251, Epyc 7252 and 62 more 2024-11-21 7.2 High
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-2020-12988 1 Amd 122 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 119 more 2024-11-21 7.5 High
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-2020-12967 1 Amd 65 Epyc 7232p, Epyc 7251, Epyc 7252 and 62 more 2024-11-21 7.2 High
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-2020-12966 1 Amd 214 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 211 more 2024-11-21 5.5 Medium
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-2020-12944 1 Amd 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more 2024-11-21 7.8 High
Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution.
CVE-2019-9836 2 Amd, Opensuse 16 Epyc 7251, Epyc 7261, Epyc 7281 and 13 more 2024-11-21 5.3 Medium
