Ryzen 5300g Firmware Security Vulnerabilities

CVE-2020-12965

When combined with specific software sequences, AMD CPUs may transiently execute non-canonical loads and store using only the lower 48 address bits potentially resulting in data leakage.

CVE-2021-26317

Failure to verify the protocol in SMM may allow an attacker to control the protocol and modify SPI flash resulting in a potential arbitrary code execution.

CVE-2021-26337

Insufficient DRAM address validation in System Management Unit (SMU) may result in a DMA read from invalid DRAM address to SRAM resulting in SMU not servicing further requests.

CVE-2021-26368

Insufficient check of the process type in Trusted OS (TOS) may allow an attacker with privileges to enable a lesser privileged process to unmap memory owned by a higher privileged process resulting in a denial of service.

CVE-2021-26386

A malicious or compromised UApp or ABL may be used by an attacker to issue a malformed system call to the Stage 2 Bootloader potentially leading to corrupt memory and code execution.

CVE-2021-46749

Insufficient bounds checking in ASP (AMD SecureProcessor) may allow for an out of bounds read in SMI (System ManagementInterface) mailbox checksum calculation triggering a data abort, resulting in apotential denial of service.

CVE-2021-46753

Failure to validate the length fields of the ASP(AMD Secure Processor) sensor fusion hub headers may allow an attacker with amalicious Uapp or ABL to map the ASP sensor fusion hub region and overwritedata structures leading to a potential loss of confidentiality and integrity.

CVE-2021-46754

Insufficient input validation in the ASP (AMDSecure Processor) bootloader may allow an attacker with a compromised Uapp orABL to coerce the bootloader into exposing sensitive information to the SMU(System Management Unit) resulting in a potential loss of confidentiality andintegrity.

CVE-2021-46759

Improper syscall input validation in AMD TEE(Trusted Execution Environment) may allow an attacker with physical access andcontrol of a Uapp that runs under the bootloader to reveal the contents of theASP (AMD Secure Processor) bootloader accessible memory to a serial port,resulting in a potential l...

CVE-2021-46765

Insufficient input validation in ASP may allowan attacker with a compromised SMM to induce out-of-bounds memory reads withinthe ASP, potentially leading to a denial of service.

CVE-2021-46773

Insufficient input validation in ABL may enablea privileged attacker to corrupt ASP memory, potentially resulting in a loss ofintegrity or code execution.

CVE-2021-46792

Time-of-check Time-of-use (TOCTOU) in theBIOS2PSP command may allow an attacker with a malicious BIOS to create a racecondition causing the ASP bootloader to perform out-of-bounds SRAM reads uponan S3 resume event potentially leading to a denial of service.

CVE-2021-46794

Insufficient bounds checking in ASP (AMD SecureProcessor) may allow for an out of bounds read in SMI (System ManagementInterface) mailbox checksum calculation triggering a data abort, resulting in apotential denial of service.

CVE-2022-29277

Incorrect pointer checks within the the FwBlockServiceSmm driver can allow arbitrary RAM modifications During review of the FwBlockServiceSmm driver, certain instances of SpiAccessLib could be tricked into writing 0xff to arbitrary system and SMRAM addresses. Fixed in: INTEL Purley-R: 05.21.51.0048...

CVE-2023-20594

Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access.

CVE-2023-20597

Improper initialization of variables in the DXE driver may allow a privileged user to leak sensitive information via local access.
