CVE Description |
CVE-2023-31342 |
7.5 (High) AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H |
Improper input validation in the SMM handler may allow a privileged attacker to overwrite SMRAM, potentially leading to arbitrary code execution. |
CVE-2023-31343 |
7.5 (High) AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H |
Improper input validation in the SMM handler may allow a privileged attacker to overwrite SMRAM, potentially leading to arbitrary code execution. |
CVE-2023-31345 |
7.5 (High) AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H |
Improper input validation in the SMM handler may allow a privileged attacker to overwrite SMRAM, potentially leading to arbitrary code execution. |
CVE-2023-31352 |
6.0 (Medium) AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N |
A bug in the SEV firmware may allow an attacker with privileges to read unencrypted memory, potentially resulting in loss of guest private data. |
CVE-2023-20515 |
5.7 (Medium) AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L |
Improper access control in the fTPM driver in the trusted OS could allow a privileged attacker to corrupt system memory, potentially leading to loss of integrity, confidentiality, or availability. |
CVE-2023-20582 |
5.3 (Medium) AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:H/A:N |
Improper handling of invalid nested page table entries in the IOMMU may allow a privileged attacker to induce page table entry ( PTE) faults to bypass RMP checks in SEV-SNP, potentially leading to a loss of guest memory integrity. |
CVE-2023-31356 |
4.4 (Medium) AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N |
Incomplete system memory cleanup in SEV firmware could allow a privileged attacker to corrupt guest private memory, potentially resulting in a loss of data integrity. |
CVE-2023-31331 |
3.0 (Low) AV:L/AC:H/PR:H/UI:N/S:U/C:N/I:L/A:L |
Improper access control in the DRTM firmware could allow a privileged attacker to perform multiple driver initializations, resulting in stack memory corruption that could potentially lead to loss of integrity or availability. |
CVE-2023-20581 |
2.5 (Low) AV:L/AC:H/PR:H/UI:N/S:C/C:N/I:L/A:N |
Improper access control in the IOMMU may allow a privileged attacker to bypass RMP checks, potentially leading to a loss of guest memory integrity. |
CVE-2023-20507 |
2.3 (Low) AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N |
An integer overflow in the ASP could allow a privileged attacker to perform an out-of-bounds write, potentially resulting in loss of data integrity. |
