Vulnerabilities > AMD
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-05-09 | CVE-2021-46754 | Improper Input Validation vulnerability in AMD products Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker with a compromised Uapp or ABL to coerce the bootloader into exposing sensitive information to the SMU (System Management Unit) resulting in a potential loss of confidentiality and integrity. | 9.1 |
| 2023-05-09 | CVE-2021-46755 | Unspecified vulnerability in AMD products Failure to unmap certain SysHub mappings in error paths of the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious bootloader to exhaust the SysHub resources resulting in a potential denial of service. | 7.5 |
| 2023-05-09 | CVE-2021-46756 | Improper Input Validation vulnerability in AMD products Insufficient validation of inputs in SVC_MAP_USER_STACK in the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious Uapp or ABL to send malformed or invalid syscall to the bootloader resulting in a potential denial of service and loss of integrity. | 9.1 |
| 2023-05-09 | CVE-2021-46759 | Out-of-bounds Write vulnerability in AMD products Improper syscall input validation in AMD TEE (Trusted Execution Environment) may allow an attacker with physical access and control of a Uapp that runs under the bootloader to reveal the contents of the ASP (AMD Secure Processor) bootloader accessible memory to a serial port, resulting in a potential loss of integrity. | 6.1 |
| 2023-05-09 | CVE-2021-46760 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in AMD products A malicious or compromised UApp or ABL can send a malformed system call to the bootloader, which may result in an out-of-bounds memory access that may potentially lead to an attacker leaking sensitive information or achieving code execution. | 9.8 |
| 2023-05-09 | CVE-2021-46765 | Out-of-bounds Read vulnerability in AMD products Insufficient input validation in ASP may allow an attacker with a compromised SMM to induce out-of-bounds memory reads within the ASP, potentially leading to a denial of service. | 7.5 |
| 2023-05-09 | CVE-2021-46773 | Improper Input Validation vulnerability in AMD products Insufficient input validation in ABL may enable a privileged attacker to corrupt ASP memory, potentially resulting in a loss of integrity or code execution. | 8.8 |
| 2023-05-09 | CVE-2021-46792 | Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products Time-of-check Time-of-use (TOCTOU) in the BIOS2PSP command may allow an attacker with a malicious BIOS to create a race condition causing the ASP bootloader to perform out-of-bounds SRAM reads upon an S3 resume event potentially leading to a denial of service. | 5.9 |
| 2023-05-09 | CVE-2021-46794 | Out-of-bounds Read vulnerability in AMD products Insufficient bounds checking in ASP (AMD Secure Processor) may allow for an out of bounds read in SMI (System Management Interface) mailbox checksum calculation triggering a data abort, resulting in a potential denial of service. | 7.5 |
| 2023-05-09 | CVE-2021-26354 | Classic Buffer Overflow vulnerability in AMD products Insufficient bounds checking in ASP may allow an attacker to issue a system call from a compromised ABL which may cause arbitrary memory values to be initialized to zero, potentially leading to a loss of integrity. | 5.5 |
