DATE	CVE	VULNERABILITY TITLE	RISK
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. network high complexity amd CWE-367	5.9
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. local low complexity amd CWE-120	5.5
2023-05-09	CVE-2021-26371	Unspecified vulnerability in AMD products A compromised or malicious ABL or UApp could send a SHA256 system call to the bootloader, which may result in exposure of ASP memory to userspace, potentially leading to information disclosure. local low complexity amd	5.5
2023-05-09	CVE-2021-46775	Improper Input Validation vulnerability in AMD products Improper input validation in ABL may enable an attacker with physical access, to perform arbitrary memory overwrites, potentially leading to a loss of integrity and code execution. low complexity amd CWE-20	6.8
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. local high complexity amd	4.7
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. local low complexity amd	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. local low complexity amd CWE-668	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. local low complexity amd CWE-190	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. local low complexity amd	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. local low complexity amd CWE-345	4.4
