| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-01-11 | CVE-2021-26316 | Improper Input Validation vulnerability in AMD products Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution. | 7.8 |
| 2023-01-11 | CVE-2021-26328 | Unspecified vulnerability in AMD products Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of memory integrity for SNP guests. | 4.4 |
| 2023-01-11 | CVE-2021-26343 | Exposure of Resource to Wrong Sphere vulnerability in AMD products Insufficient validation in ASP BIOS and DRTM commands may allow malicious supervisor x86 software to disclose the contents of sensitive memory which may result in information disclosure. | 5.5 |
| 2023-01-11 | CVE-2021-26346 | Integer Overflow or Wraparound 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. | 5.5 |
| 2023-01-11 | CVE-2021-26355 | Unspecified vulnerability in AMD products Insufficient fencing and checks in System Management Unit (SMU) may result in access to invalid message port registers that could result in a potential denial-of-service. | 5.5 |
| 2023-01-11 | CVE-2021-26396 | Insufficient Verification of Data Authenticity vulnerability in AMD products Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest. | 4.4 |
| 2023-01-11 | CVE-2021-26398 | Out-of-bounds Write vulnerability in AMD products Insufficient input validation in SYS_KEY_DERIVE system call in a compromised user application or ABL may allow an attacker to corrupt ASP (AMD Secure Processor) OS memory which may lead to potential arbitrary code execution. | 7.8 |
| 2023-01-11 | CVE-2021-26402 | Out-of-bounds Write vulnerability in AMD products Insufficient bounds checking in ASP (AMD Secure Processor) firmware while handling BIOS mailbox commands, may allow an attacker to write partially-controlled data out-of-bounds to SMM or SEV-ES regions which may lead to a potential loss of integrity and availability. | 7.1 |
| 2023-01-11 | CVE-2021-26403 | Unspecified vulnerability in AMD products Insufficient checks in SEV may lead to a malicious hypervisor disclosing the launch secret potentially resulting in compromise of VM confidentiality. | 6.5 |
| 2023-01-11 | CVE-2021-26404 | Improper Input Validation vulnerability in AMD products Improper input validation and bounds checking in SEV firmware may leak scratch buffer bytes leading to potential information disclosure. | 5.5 |
