An integer overflow in the SMU could allow a privileged attacker to potentially write memory beyond the end of the reserved dRAM area resulting in loss of integrity or availability.

Improper restriction of operations in the IOMMU could allow a malicious hypervisor to access guest private memory resulting in loss of integrity.

An out-of-bounds read in the ASP could allow a privileged attacker with access to a malicious bootloader to potentially read sensitive memory resulting in loss of confidentiality.

Use of an uninitialized variable in the ASP could allow an attacker to access leftover data from a trusted execution environment (TEE) driver, potentially leading to loss of confidentiality.

Improper isolation of shared resources on System-on-a-chip (SOC) could a privileged attacker to tamper with the contents of the PSP reserved DRAM region potentially resulting in loss of confidentiality and integrity.

Type confusion in the ASP could allow an attacker to pass a malformed argument to the Reliability, Availability, and Serviceability trusted application (RAS TA) potentially leading to a read or write to shared memory resulting in loss of confidentiality, integrity, or availability.

Improper validation of an array index in the AMD graphics driver software could allow an attacker to pass malformed arguments to the dynamic power management (DPM) functions resulting in an out of bounds read and loss of availability.

Improper handling of insufficiency privileges in the ASP could allow a privileged attacker to modify Translation Map Registers (TMRs) potentially resulting in loss of confidentiality or integrity.

Failure to validate the address and size in TEE (Trusted Execution Environment) may allow a malicious x86 attacker to send malformed messages to the graphics mailbox resulting in an overlap of a TMR (Trusted Memory Region) that was previously allocated by the ASP bootloader leading to a potential l…

Insufficient parameter validation while allocating process space in the Trusted OS (TOS) may allow for a malicious userspace process to trigger an integer overflow, leading to a potential denial of service.
