🚨 CVE-2021-26387
Insufficient access controls in ASP kernel may allow a
privileged attacker with access to AMD signing keys and the BIOS menu or UEFI
shell to map DRAM regions in protected areas, potentially leading to a loss of platform integrity.

🎖@cveNotify
🚨 CVE-2021-46746
Lack of stack protection exploit mechanisms in ASP Secure OS Trusted Execution Environment (TEE) may allow a privileged attacker with access to AMD signing
keys to c006Frrupt the return address, causing a
stack-based buffer overrun, potentially leading to a denial of service.

🚨 CVE-2021-46772
Insufficient input validation in the ABL may allow a privileged
attacker with access to the BIOS menu or UEFI shell to tamper with the
structure headers in SPI ROM causing an out of bounds memory read and write,
potentially resulting in memory corruption or denial of service.

🚨 CVE-2022-23815
Improper bounds checking in APCB firmware may allow an attacker to perform an out of bounds write, corrupting the APCB entry, potentially leading to arbitrary code execution.

🚨 CVE-2022-23817
Insufficient checking of memory buffer in ASP Secure OS may allow an attacker with a malicious TA to read/write to the ASP Secure OS kernel virtual address space, potentially leading to privilege escalation.

🚨 CVE-2023-20509
An insufficient DRAM address validation in PMFW may allow a privileged attacker to perform a DMA read from an invalid DRAM address to SRAM, potentially resulting in loss of data integrity.

🚨 CVE-2023-20510
An insufficient DRAM address validation in PMFW may allow a privileged attacker to read from an invalid DRAM address to SRAM, potentially resulting in data corruption or denial of service.

🚨 CVE-2023-20512
A hardcoded AES key in PMFW may result in a privileged attacker gaining access to the key, potentially resulting in internal debug information leakage.

🎖@cveNotify
🚨 CVE-2023-20513
An insufficient bounds check in PMFW (Power Management Firmware) may allow an attacker to utilize a malicious VF (virtualization function) to send a malformed message, potentially resulting in a denial of service.

🎖@cveNotify
🚨 CVE-2023-20518
Incomplete cleanup in the ASP may expose the Master Encryption Key (MEK) to a privileged attacker with access to the BIOS menu or UEFI shell and a memory exfiltration vulnerability, potentially resulting in loss of confidentiality.

🎖@cveNotify
🚨 CVE-2023-20578
A TOCTOU (Time-Of-Check-Time-Of-Use) in SMM may allow
an attacker with ring0 privileges and access to the
BIOS menu or UEFI shell to modify the communications buffer potentially
resulting in arbitrary code execution.

🎖@cveNotify
🚨 CVE-2023-20584
IOMMU improperly handles certain special address
ranges with invalid device table entries (DTEs), which may allow an attacker
with privileges and a compromised Hypervisor to
induce DTE faults to bypass RMP checks in SEV-SNP, potentially leading to a
loss of guest integrity.

🎖@cveNotify
🚨 CVE-2023-20591
Improper re-initialization of IOMMU during the DRTM event
may permit an untrusted platform configuration to persist, allowing an attacker
to read or modify hypervisor memory, potentially resulting in loss of
confidentiality, integrity, and availability.

🎖@cveNotify
🚨 CVE-2023-31304
Improper input validation in SMU may allow an attacker with privileges and a compromised physical function (PF)     to modify the PCIe® lane count and speed, potentially leading to a loss of availability.

🚨 CVE-2024-20082
In Modem, there is a possible memory corruption due to a missing bounds check. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01182594; Issue ID: MSV-1529.

🎖@cveNotify
🚨 CVE-2024-20083
In venc, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08810810 / ALPS08805789; Issue ID: MSV-1502.
