Epyc 7742 Firmware

DATE	CVE	VULNERABILITY TITLE	RISK
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
2023-05-09	CVE-2023-20520	Out-of-bounds Write vulnerability in AMD products Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution. network low complexity amd CWE-787 critical	9.8
2023-05-09	CVE-2023-20524	Out-of-bounds Write vulnerability in AMD products An attacker with a compromised ASP could possibly send malformed commands to an ASP on another CPU, resulting in an out of bounds write, potentially leading to a loss a loss of integrity. network low complexity amd CWE-787	7.5
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-2021-26316	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. local low complexity amd CWE-20	7.8
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-2021-26403	Unspecified vulnerability in AMD products Insufficient checks in SEV may lead to a malicious hypervisor disclosing the launch secret potentially resulting in compromise of VM confidentiality. local low complexity amd	6.5
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
