| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-01-11 | CVE-2023-20528 | Improper Input Validation vulnerability in AMD products Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory contents over the I2C bus potentially leading to a loss of confidentiality. | 2.4 |
| 2023-01-11 | CVE-2023-20529 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks in the SMU may allow an attacker to update the from/to address space to an invalid value potentially resulting in a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20530 | Improper Input Validation vulnerability in AMD products Insufficient input validation of BIOS mailbox messages in SMU may result in out-of-bounds memory reads potentially resulting in a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20531 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products Insufficient bound checks in the SMU may allow an attacker to update the SRAM from/to address space to an invalid value potentially resulting in a denial of service. | 7.5 |
| 2023-01-11 | CVE-2023-20532 | Improper Input Validation vulnerability in AMD products Insufficient input validation in the SMU may allow an attacker to improperly lock resources, potentially resulting in a denial of service. | 5.3 |
| 2022-11-09 | CVE-2022-23824 | IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. | 5.5 |
| 2022-08-10 | CVE-2021-46778 | Information Exposure Through Discrepancy vulnerability in AMD products 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). | 5.6 |
| 2022-05-11 | CVE-2021-26339 | Unspecified vulnerability in AMD products 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. | 5.5 |
| 2022-05-11 | CVE-2021-26342 | Unspecified vulnerability in AMD products 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). | 3.3 |
| 2022-05-11 | CVE-2021-26347 | Improper Validation of Specified Quantity in Input vulnerability in AMD products Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service. | 4.7 |
