An exploitable memory corruption vulnerability exists in AMD ATIDXX64.DLL driver, versions 25.20.15031.5004 and 25.20.15031.9002. A specially crafted pixel shader can cause an out-of-bounds memory write. An attacker can provide a specially crafted shader file to trigger this vulnerability. This vulnerability can be triggered from VMware guest, affecting VMware host.

An exploitable code execution vulnerability exists in the Shader functionality of AMD Radeon DirectX 11 Driver atidxx64.dll 26.20.15019.19000. An attacker can provide a a specially crafted shader file to trigger this vulnerability, resulting in code execution. This vulnerability can be triggered from a HYPER-V guest using the RemoteFX feature, leading to executing the vulnerable code on the HYPER-V host (inside of the rdvgm.exe process). Theoretically this vulnerability could be also triggered from web browser (using webGL and webassembly).

An exploitable memory corruption vulnerability exists in AMD atidxx64.dll 26.20.15019.19000 graphics driver. A specially crafted pixel shader can cause memory corruption vulnerability. An attacker can provide a specially crafted shader file to trigger this vulnerability. This vulnerability potentially could be triggered from guest machines running virtualization environments (ie. VMware, qemu, VirtualBox etc.) in order to perform guest-to-host escape - as it was demonstrated before (TALOS-2018-0533, TALOS-2018-0568, etc.). Theoretically this vulnerability could be also triggered from web browser (using webGL and webassembly). This vulnerability was triggered from HYPER-V guest using RemoteFX feature leading to executing the vulnerable code on the HYPER-V host (inside of the rdvgm.exe process).

The AMDPowerProfiler.sys driver of AMD ?Prof tool may allow lower privileged users to access MSRs in kernel which may lead to privilege escalation and ring-0 code execution by the lower privileged user.

An issue was discovered in AODDriver2.sys in AMD OverDrive. The vulnerable driver exposes a wrmsr instruction via IOCTL 0x81112ee0 and does not properly filter the Model Specific Register (MSR). Allowing arbitrary MSR writes can lead to Ring-0 code execution and escalation of privileges.

A potential vulnerability was reported in Radeon™ Software Crimson ReLive Edition which may allow escalation of privilege. Radeon™ Software Crimson ReLive Edition falls outside of the security support lifecycle and AMD does not plan to release any mitigations

A malicious or compromised UApp or ABL can send a malformed system call to the bootloader, which may result in an out-of-bounds memory access that may potentially lead to an attacker leaking sensitive information or achieving code execution.

Insufficient input validation of mailbox data in the SMU may allow an attacker to coerce the SMU to corrupt SMRAM, potentially leading to a loss of integrity and privilege escalation.

Improper access control settings in ASP Bootloader may allow an attacker to corrupt the return address causing a stack-based buffer overrun potentially leading to arbitrary code execution.

A stack buffer overflow vulnerability discovered in AsfSecureBootDxe in Insyde InsydeH2O with kernel 5.0 through 5.5 allows attackers to run arbitrary code execution during the DXE phase.

Failure to validate the AMD SMM communication buffer may allow an attacker to corrupt the SMRAM potentially leading to arbitrary code execution.

Improper input validation in the SMM Supervisor may allow an attacker with a compromised SMI handler to gain Ring0 access potentially leading to arbitrary code execution.

Improper access control in System Management Mode (SMM) may allow an attacker to write to SPI ROM potentially leading to arbitrary code execution.

The Promontory chipset, as used in AMD Ryzen and Ryzen Pro platforms, has a backdoor in firmware, aka CHIMERA-FW.

The AMD EPYC Server processor chips have insufficient access control for protected memory regions, aka FALLOUT-1, FALLOUT-2, and FALLOUT-3.

The AMD EPYC Server, Ryzen, Ryzen Pro, and Ryzen Mobile processor chips allow Platform Security Processor (PSP) privilege escalation.

The AMD EPYC Server, Ryzen, Ryzen Pro, and Ryzen Mobile processor chips have insufficient enforcement of Hardware Validated Boot, aka MASTERKEY-1, MASTERKEY-2, and MASTERKEY-3.

The AMD Ryzen and Ryzen Pro processor chips have insufficient access control for the Secure Processor, aka RYZENFALL-2, RYZENFALL-3, and RYZENFALL-4.

Unrestricted IP address binding in the AMD Device Metrics Exporter (ROCm ecosystem) could allow a remote attacker to perform unauthorized changes to the GPU configuration, potentially resulting in loss of availability

AI Tensor Engine for ROCm (AITER) through 0.1.14 contains an unauthenticated remote code execution vulnerability in the MessageQueue.recv() function within shmbroadcast.py that allows unauthenticated remote attackers to execute arbitrary code by sending a malicious pickle payload to a ZMQ SUB socket with no authentication, HMAC, or format validation. Attackers who can reach the writer XPUB endpoint on the cluster network or supply a forged Handle with an attacker-controlled remotesubscribeaddr can deliver a crafted pickle payload that executes arbitrary code simultaneously as the inference worker process on every remote reader worker.

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

Insufficient validation of inputs in SVCMAPUSERSTACK in the ASP (AMD Secure Processor) bootloader may allow an attacker with a malicious Uapp or ABL to send malformed or invalid syscall to the bootloader resulting in a potential denial of service and loss of integrity.

Insufficient input validation in the SMU may allow an attacker to corrupt SMU SRAM potentially leading to a loss of integrity or denial of service.

Insufficient input validation in the ASP (AMD Secure Processor) bootloader may allow an attacker with a compromised Uapp or ABL to coerce the bootloader into exposing sensitive information to the SMU (System Management Unit) resulting in a potential loss of confidentiality and integrity.

AMD ATI atillk64.sys 5.11.9.0 allows low-privileged users to interact directly with physical memory by calling one of several driver routines that map physical memory into the virtual address space of the calling process. This could enable low-privileged users to achieve NT AUTHORITY\SYSTEM privileges via a DeviceIoControl call associated with MmMapIoSpace, IoAllocateMdl, MmBuildMdlForNonPagedPool, or MmMapLockedPages.
