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. |
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. |
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 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. |
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 Whitley: 05.42.23.0066 Cedar Island: 05.42.11.0021 Eagle Stream: 05.44.25.0052 Greenlow/Greenlow-R(skylake/kabylake): Trunk Mehlow/Mehlow-R (CoffeeLake-S): Trunk Tatlow (RKL-S): Trunk Denverton: 05.10.12.0042 Snow Ridge: Trunk Graneville DE: 05.05.15.0038 Grangeville DE NS: 05.27.26.0023 Bakerville: 05.21.51.0026 Idaville: 05.44.27.0030 Whiskey Lake: Trunk Comet Lake-S: Trunk Tiger Lake H/UP3: 05.43.12.0052 Alder Lake: 05.44.23.0047 Gemini Lake: Not Affected Apollo Lake: Not Affected Elkhart Lake: 05.44.30.0018 AMD ROME: trunk MILAN: 05.36.10.0017 GENOA: 05.52.25.0006 Snowy Owl: Trunk R1000: 05.32.50.0018 R2000: 05.44.30.0005 V2000: Trunk V3000: 05.44.30.0007 Ryzen 5000: 05.44.30.0004 Embedded ROME: Trunk Embedded MILAN: Trunk Hygon Hygon #1/#2: 05.36.26.0016 Hygon #3: 05.44.26.0007 https://www.insyde.com/security-pledge/SA-2022060 |
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. |
Failure to validate the integer operand in ASP (AMD Secure Processor) bootloader may allow an attacker to introduce an integer overflow in the L2 directory table in SPI flash resulting in a potential denial of service. |
Failure to validate the communication buffer and communication service in the BIOS may allow an attacker to tamper with the buffer resulting in potential SMM (System Management Mode) arbitrary code execution. |
Failure to validate privileges during installation of AMD Ryzen™ Master may allow an attacker with low
privileges to modify files potentially leading to privilege escalation and code execution by the lower
privileged user.
|
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. |
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. |
Improper
Access Control in the AMD SPI protection feature may allow a user with Ring0
(kernel mode) privileged access to bypass protections potentially resulting in
loss of integrity and availability.
|
Insufficient control flow management in AmdCpmGpioInitSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to escalation of privileges.
|
Insufficient control flow management in AmdCpmOemSmm may allow a privileged attacker to tamper with the SMM handler potentially leading to an escalation of privileges.
|
An issue in “Zen 2” CPUs, under specific microarchitectural circumstances, may allow an attacker to potentially access sensitive information. |
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. |
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. |
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. |
IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. |
