Vulnerabilities > AMD > Ryzen 5 5500U Firmware
| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2023-03-01 | CVE-2022-27672 | Unspecified vulnerability in AMD products When SMT is enabled, certain AMD processors may speculatively execute instructions using a target from the sibling thread after an SMT mode switch potentially resulting in information disclosure. | 4.7 |
| 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-2021-26346 | 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 |
| 2022-11-09 | CVE-2020-12930 | Unspecified vulnerability in AMD products Improper parameters handling in AMD Secure Processor (ASP) drivers may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity. | 7.8 |
| 2022-11-09 | CVE-2020-12931 | Unspecified vulnerability in AMD products Improper parameters handling in the AMD Secure Processor (ASP) kernel may allow a privileged attacker to elevate their privileges potentially leading to loss of integrity. | 7.8 |
| 2022-11-09 | CVE-2021-26391 | Unspecified vulnerability in AMD products Insufficient verification of multiple header signatures while loading a Trusted Application (TA) may allow an attacker with privileges to gain code execution in that TA or the OS/kernel. | 7.8 |
| 2022-11-09 | CVE-2021-26392 | Out-of-bounds Write vulnerability in AMD products Insufficient verification of missing size check in 'LoadModule' may lead to an out-of-bounds write potentially allowing an attacker with privileges to gain code execution of the OS/kernel by loading a malicious TA. | 7.8 |
| 2022-11-09 | CVE-2021-26393 | Memory Leak vulnerability in AMD products Insufficient memory cleanup in the AMD Secure Processor (ASP) Trusted Execution Environment (TEE) may allow an authenticated attacker with privileges to generate a valid signed TA and potentially poison the contents of the process memory with attacker controlled data resulting in a loss of confidentiality. | 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-2021-26388 | Out-of-bounds Read vulnerability in AMD products Improper validation of the BIOS directory may allow for searches to read beyond the directory table copy in RAM, exposing out of bounds memory contents, resulting in a potential denial of service. | 5.5 |
