CVE-2021-46754 1 Amd 112 Athlon Gold 3150g, Athlon Gold 3150g Firmware, Athlon Gold 3150ge and 109 more 2024-11-21 9.1 Critical
Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker with a compromised Uapp or ABL to coerce the bootloader into exposing sensitive information to the SMU (System Management Unit) resulting in a potential loss of confidentiality and integrity.
CVE-2021-46744 1 Amd 198 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 195 more 2024-11-21 6.5 Medium
An attacker with access to a malicious hypervisor may be able to infer data values used in a SEV guest on AMD CPUs by monitoring ciphertext values over time.
CVE-2021-44850 1 Amd 20 Xilinx Z-7007s, Xilinx Z-7007s Firmware, Xilinx Z-7010 and 17 more 2024-11-21 6.8 Medium
On Xilinx Zynq-7000 SoC devices, physical modification of an SD boot image allows for a buffer overflow attack in the ROM. Because the Zynq-7000's boot image header is unencrypted and unauthenticated before use, an attacker can modify the boot header stored on an SD card so that a secure image appears to be unencrypted, and they will be able to modify the full range of register initialization values. Normally, these registers will be restricted when booting securely. Of importance to this attack are two registers that control the SD card's transfer type and transfer size. These registers could be modified a way that causes a buffer overflow in the ROM.
CVE-2021-26409 1 Amd 2 Milanpi, Milanpi Firmware 2024-11-21 7.8 High
Insufficient bounds checking in SEV-ES may allow an attacker to corrupt Reverse Map table (RMP) memory, potentially resulting in a loss of SNP (Secure Nested Paging) memory integrity.
CVE-2021-26408 1 Amd 76 Epyc 7001, Epyc 7001 Firmware, Epyc 7002 and 73 more 2024-11-21 7.1 High
Insufficient validation of elliptic curve points in SEV-legacy firmware may compromise SEV-legacy guest migration potentially resulting in loss of guest's integrity or confidentiality.
CVE-2021-26407 1 Amd 2 Romepi, Romepi Firmware 2024-11-21 5.5 Medium
A randomly generated Initialization Vector (IV) may lead to a collision of IVs with the same key potentially resulting in information disclosure.
CVE-2021-26404 1 Amd 46 Epyc 7003, Epyc 7003 Firmware, Epyc 7313 and 43 more 2024-11-21 5.5 Medium

CVE-2021-26402 1 Amd 100 Epyc 7002, Epyc 7002 Firmware, Epyc 7003 and 97 more 2024-11-21 7.1 High
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.
CVE-2021-26401 2 Amd, Redhat 255 A10-9600p, A10-9600p Firmware, A10-9630p and 252 more 2024-11-21 5.6 Medium
