A GPU kernel can read sensitive data from another GPU kernel (even from another user or app) through an optimized GPU memory region called _local memory_ on various architectures.
Improper input validation in the AMD RadeonTM Graphics display driver may allow an attacker to corrupt the display potentially resulting in denial of service.
Improper signature verification of RadeonTM RX Vega M Graphics driver for Windows may allow an attacker with admin privileges to launch AMDSoftwareInstaller.exe without validating the file signature potentially leading to arbitrary code execution.
Improper signature verification of RadeonTM RX Vega M Graphics driver for Windows may allow an attacker with admin privileges to launch RadeonInstaller.exe without validating the file signature potentially leading to arbitrary code execution.
Insufficient bounds checking in the ASP (AMD Secure Processor) may allow an attacker to access memory outside the bounds of what is permissible to a TA (Trusted Application) resulting in a potential denial of service.
Insufficient validation of SPI flash addresses in the ASP (AMD Secure Processor) bootloader may allow an attacker to read data in memory mapped beyond SPI flash resulting in a potential loss of availability and integrity.
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.
Insufficient input validation in
CpmDisplayFeatureSmm may allow an attacker to corrupt SMM memory by overwriting
an arbitrary bit in an attacker-controlled pointer potentially leading to
arbitrary code execution in SMM.
A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure.
An attacker with specialized hardware and physical access to an impacted device may be able to perform a voltage fault injection attack resulting in compromise of the ASP secure boot potentially leading to arbitrary code execution.Â
