7.5CVE-2023-20533amd2nd gen amd epyc™ processors+96
EPSS score
0.50%
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.
7.5CVE-2023-20566amd3rd gen amd epyc™ processors+68
EPSS score
0.37%
Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity.
7.5CVE-2023-20524amd2nd gen amd epyc™+49
EPSS score
0.49%
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.
6.5CVE-2023-20592amd1st gen amd epyc™ processors+91
EPSS score
1.02%
Improper or unexpected behavior of the INVD instruction in some AMD CPUs may allow an attacker with a malicious hypervisor to affect cache line write-back behavior of the CPU leading to a potential loss of guest virtual machine (VM) memory integrity.
5.7CVE-2023-20521amd1st gen amd epyc™ processors+106
EPSS score
0.26%
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.
9.8CVE-2023-20520amd1st gen amd epyc™+65
EPSS score
0.79%
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.
7.5CVE-2023-20578amdepyc_7001_firmware+104
EPSS score
0.12%
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.
10CVE-2023-20591amdepyc_7203_firmware+64
EPSS score
0.30%
Improper re-initialization of IOMMU during the DRTM event may permit an untrusted platform configuration to persist, allowing an attacker to read or modify hypervisor memory, potentially resulting in loss of confidentiality, integrity, and availability.
4.7CVE-2023-20569amd1st gen amd epyc™ processors+338
EPSS score
7.30%
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.
4.6CVE-2023-20526amd1st gen amd epyc™ processors+79
EPSS score
0.31%
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.
3.2CVE-2023-20573amd3rd gen amd epyc™ processors+66
EPSS score
0.29%
A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information.
6.5CVE-2023-20575amd1st gen amd epyc™ processors+91
EPSS score
0.80%
A potential power side-channel vulnerability in some AMD processors may allow an authenticated attacker to use the power reporting functionality to monitor a program’s execution inside an AMD SEV VM potentially resulting in a leak of sensitive information.
4.9CVE-2023-31347amd3rd gen amd epyc™ processors+64
EPSS score
0.46%
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.
6CVE-2023-31346amd3rd gen amd epyc™ processors+87
EPSS score
0.31%
Failure to initialize memory in SEV Firmware may allow a privileged attacker to access stale data from other guests.
6CVE-2023-31355amd3rd gen amd epyc™ processors+89
EPSS score
0.44%
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to overwrite a guest's UMC seed potentially allowing reading of memory from a decommissioned guest.
