Epyc 7643 Firmware

DATE	CVE	VULNERABILITY TITLE	RISK
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-2021-26355	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
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. local low complexity amd CWE-787	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. local low complexity amd CWE-787	7.1
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. local low complexity amd CWE-20	5.5
2023-01-11	CVE-2023-20523	Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products TOCTOU in the ASP may allow a physical attacker to write beyond the buffer bounds, potentially leading to a loss of integrity or denial of service. high complexity amd CWE-367	5.7
2023-01-11	CVE-2023-20525	Improper Input Validation vulnerability in AMD products Insufficient syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory outside the bounds of a mapped register potentially leading to a denial of service. network low complexity amd CWE-20	6.5
2023-01-11	CVE-2023-20527	Improper Input Validation vulnerability in AMD products Improper syscall input validation in the ASP Bootloader may allow a privileged attacker to read memory out-of-bounds, potentially leading to a denial-of-service. network low complexity amd CWE-20	6.5
