Failure to validate inputs in SMM may allow an attacker to create a mishandled error leaving the DRTM UApp in a partially initialized state potentially resulting in loss of memory integrity.
CVE-2022-23823 1 Amd 284 A10-9600p, A10-9600p Firmware, A10-9630p and 281 more 2023-12-10 4.0 MEDIUM 6.5 MEDIUM
A potential vulnerability in some AMD processors using frequency scaling may allow an authenticated attacker to execute a timing attack to potentially enable information disclosure.
CVE-2021-44850 1 Amd 20 Xilinx Z-7007s, Xilinx Z-7007s Firmware, Xilinx Z-7010 and 17 more 2023-12-10 4.6 MEDIUM 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-2021-26366 1 Amd 125 Athlon 3050ge, Athlon 3050ge Firmware, Athlon 3150g and 122 more 2023-12-10 3.6 LOW 7.1 HIGH
An attacker, who gained elevated privileges via some other vulnerability, may be able to read data from Boot ROM resulting in a loss of system integrity.
CVE-2021-26341 1 Amd 252 A10-9600p, A10-9600p Firmware, A10-9630p and 249 more 2023-12-10 2.1 LOW 6.5 MEDIUM
Some AMD CPUs may transiently execute beyond unconditional direct branches, which may potentially result in data leakage.
CVE-2021-26378 1 Amd 167 Epyc 7232p, Epyc 7232p Firmware, Epyc 7252 and 164 more 2023-12-10 4.9 MEDIUM 5.5 MEDIUM
Insufficient bound checks in the System Management Unit (SMU) may result in access to an invalid address space that could result in denial of service.
