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-2021-26342 1 Amd 76 Epyc 7001, Epyc 7001 Firmware, Epyc 7251 and 73 more 2022-05-19 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-2021-26408 1 Amd 76 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 73 more 2022-05-17 7.1 High

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-2020-12951 1 Amd 116 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 113 more 2022-05-12 7.0 High
