CVE-2023-20526 [MEDIUM] CVE-2023-20526: Insufficient input validation in the ASP Bootloader may enable a privileged attacker with physical a 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.

CVE-2021-26347 [MEDIUM] CWE-1284 CVE-2021-26347: Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attack Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service.

CVE-2021-26396 [MEDIUM] CWE-345 CVE-2021-26396: Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss Insufficient validation of address mapping to IO in ASP (AMD Secure Processor) may result in a loss of memory integrity in the SNP guest.

CVE-2021-26328 [MEDIUM] CWE-358 CVE-2021-26328: Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of Failure to verify the mode of CPU execution at the time of SNP_INIT may lead to a potential loss of memory integrity for SNP guests.

CVE-2023-20594 [MEDIUM] CWE-824 CVE-2023-20594: Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access.

CVE-2021-26350 [MEDIUM] CWE-367 CVE-2021-26350: A TOCTOU race condition in SMU may allow for the caller to obtain and manipulate the address of a me A TOCTOU race condition in SMU may allow for the caller to obtain and manipulate the address of a message port register which may result in a potential denial of service.

CVE-2021-26342 [LOW] CVE-2021-26342: In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a parti In SEV guest VMs, the CPU may fail to flush the Translation Lookaside Buffer (TLB) following a particular sequence of operations that includes creation of a new virtual machine control block (VMCB). The failure to flush the TLB may cause the microcode to use stale TLB translations which may allow for disclosure of SEV guest memory contents. Users of SEV-ES/SEV

CVE-2023-20528 [LOW] CWE-20 CVE-2023-20528: Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory cont Insufficient input validation in the SMU may allow a physical attacker to exfiltrate SMU memory contents over the I2C bus potentially leading to a loss of confidentiality.
