Improper input validation within AMD uprof can allow a local attacker to overwrite MSR registers, potentially resulting in crash or denial of service.

Improper return value within AMD uProf can allow a local attacker to bypass KSLR, potentially resulting in loss of confidentiality or availability.

Improper input validation within AMD uprof can allow a local attacker to write to an arbitrary physical address, potentially resulting in crash or denial of service.

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

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

GPU kernel implementations susceptible to memory leak

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.

Debug Exception Delivery in Secure Nested Paging

A privileged attacker can prevent delivery of debug exceptions to SEV-SNP guests potentially resulting in guests not receiving expected debug information.

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.

Insufficient validation in the IOCTL input/output buffer in AMD μProf may allow an attacker to bypass bounds checks potentially leading to a Windows kernel crash resulting in denial of service.

Insufficient validation of the IOCTL input buffer in AMD μProf may allow an attacker to send an arbitrary buffer leading to a potential Windows kernel crash resulting in denial of service.

hw: amd: Insufficient verification of header signature may lead to unwanted code execution problem

Insufficient verification of multiple header signatures while loading a Trusted Application (TA) may allow an attacker with privileges to gain code execution in that TA or the OS/kernel.

hw: amd: Unauthorized modifications of the security configuration of the SOC registers

An attacker with local access to the system can make unauthorized modifications of the security configuration of the SOC registers. This could allow potential corruption of AMD secure processor’s encrypted memory contents which may lead to arbitrary code execution in ASP.

Insufficient access controls in the AMD Link Android app may potentially result in information disclosure.

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.

The AMD Ryzen processor with AGESA microcode through 2017-01-27 allows local users to cause a denial of service (system hang) via an application that makes a long series of FMA3 instructions, as demonstrated by the Flops test suite.

AMD fglrx-driver before 15.7 allows local users to gain privileges via a symlink attack.

Page table walks conducted by the MMU during virtual to physical address translation leave a trace in the last level cache of modern ARM processors. By performing a side-channel attack on the MMU operations, it is possible to leak data and code pointers from JavaScript, breaking ASLR.
