Epyc 7643 Firmware

DATE	CVE	VULNERABILITY TITLE	RISK
2024-08-13	CVE-2023-20578	Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow an attacker with ring0 privileges and access to the BIOS menu or UEFI shell to modify the communications buffer potentially resulting in arbitrary code execution. local high complexity amd CWE-367	6.4
2024-02-13	CVE-2023-31346	Unspecified vulnerability in AMD products Failure to initialize memory in SEV Firmware may allow a privileged attacker to access stale data from other guests. local low complexity amd	6.0
2024-02-13	CVE-2023-31347	Unspecified vulnerability in AMD products Due to a code bug in Secure_TSC, SEV firmware may allow an attacker with high privileges to cause a guest to observe an incorrect TSC when Secure TSC is enabled potentially resulting in a loss of guest integrity. network low complexity amd	4.9
2024-01-11	CVE-2023-20573	Unspecified vulnerability in AMD products A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information. local low complexity amd	3.2
2023-11-14	CVE-2021-26345	Out-of-bounds Read vulnerability in AMD products Failure to validate the value in APCB may allow a privileged attacker to tamper with the APCB token to force an out-of-bounds memory read potentially resulting in a denial of service. network low complexity amd CWE-125	4.9
2023-11-14	CVE-2021-46774	Unspecified vulnerability in AMD products Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service. network low complexity amd	7.5
2023-11-14	CVE-2022-23830	Unspecified vulnerability in AMD products SMM configuration may not be immutable, as intended, when SNP is enabled resulting in a potential limited loss of guest memory integrity. network low complexity amd	5.3
2023-11-14	CVE-2023-20521	Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in AMD products TOCTOU in the ASP Bootloader may allow an attacker with physical access to tamper with SPI ROM records after memory content verification, potentially leading to loss of confidentiality or a denial of service. high complexity amd CWE-367	5.7
2023-11-14	CVE-2023-20526	Unspecified vulnerability in AMD products Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical access to expose the contents of ASP memory potentially leading to a loss of confidentiality. low complexity amd	4.6
2023-11-14	CVE-2023-20533	Unspecified vulnerability in AMD products Insufficient DRAM address validation in System Management Unit (SMU) may allow an attacker to read/write from/to an invalid DRAM address, potentially resulting in denial-of-service. network low complexity amd	7.5
