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-2021-26342 | 1 Amd | 76 Epyc 7001, Epyc 7001 Firmware, Epyc 7251 and 73 more | 2024-02-28 | 2.1 LOW | 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-2021-46744 | 1 Amd | 198 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 195 more | 2024-02-28 | 2.1 LOW | 6.5 MEDIUM |
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-2022-23823 | 1 Amd | 284 A10-9600p, A10-9600p Firmware, A10-9630p and 281 more | 2024-02-28 | 4.0 MEDIUM | 6.5 MEDIUM |
