Epyc 7643P Firmware
Monthly
Improper restriction of write operations in SNP firmware could allow a malicious hypervisor to potentially overwrite a guest's memory or UMC seed resulting in loss of confidentiality and integrity. Rated high severity (CVSS 7.9), this vulnerability is low attack complexity. No vendor patch available.
Improper input validation in SEV-SNP could allow a malicious hypervisor to read or overwrite guest memory potentially leading to data leakage or data corruption. Rated high severity (CVSS 7.9), this vulnerability is low attack complexity. No vendor patch available.
A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information. Rated low severity (CVSS 3.2), this vulnerability is low attack complexity. No vendor patch available.
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. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
Improper address validation in ASP with SNP enabled may potentially allow an attacker to compromise guest memory integrity. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
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. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
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. Rated medium severity (CVSS 4.6), this vulnerability is no authentication required, low attack complexity. No vendor patch available.
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. Rated medium severity (CVSS 5.7), this vulnerability is no authentication required. No vendor patch available.
