CVE-2020-12966 | 1 Amd | 214 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 211 more | 2024-02-04 | 2.1 LOW | 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-2021-26320 | 1 Amd | 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more | 2024-02-04 | 2.1 LOW | 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 | 2024-02-04 | 2.1 LOW | 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-2020-12944 | 1 Amd | 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more | 2024-02-04 | 4.6 MEDIUM | 7.8 HIGH |
Insufficient validation of BIOS image length by ASP Firmware could lead to arbitrary code execution. | |||||
CVE-2021-26340 | 1 Amd | 210 Epyc 7001, Epyc 7001 Firmware, Epyc 7232p and 207 more | 2024-02-04 | 3.6 LOW | 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-2021-26322 | 1 Amd | 114 Epyc 7232p, Epyc 7232p Firmware, Epyc 7251 and 111 more | 2024-02-04 | 5.0 MEDIUM | 7.5 HIGH |
Persistent platform private key may not be protected with a random IV leading to a potential “two time pad attack”. | |||||
CVE-2020-12988 | 1 Amd | 122 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 119 more | 2024-02-04 | 7.8 HIGH | 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-2021-26311 | 1 Amd | 65 Epyc 7232p, Epyc 7251, Epyc 7252 and 62 more | 2024-02-04 | 9.0 HIGH | 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-2020-12967 | 1 Amd | 65 Epyc 7232p, Epyc 7251, Epyc 7252 and 62 more | 2024-02-04 | 9.0 HIGH | 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-2019-9836 | 2 Amd, Opensuse | 16 Epyc 7251, Epyc 7261, Epyc 7281 and 13 more | 2024-02-04 | 5.0 MEDIUM | 5.3 MEDIUM |
Secure Encrypted Virtualization (SEV) on Advanced Micro Devices (AMD) Platform Security Processor (PSP; aka AMD Secure Processor or AMD-SP) 0.17 build 11 and earlier has an insecure cryptographic implementation. | |||||
CVE-2022-29900 | 4 Amd, Debian, Fedoraproject and 1 more | 249 A10-9600p, A10-9600p Firmware, A10-9630p and 246 more | 2024-02-04 | 2.1 LOW | 6.5 MEDIUM |
Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. | |||||
