Vulnerabilidades de AMD

Improper verification of cryptographic signature in the Radeon RGB tool could allow a malicious file placed in the installation directory to be run with elevated privileges potentially leading to arbitrary code execution.

A DLL hijacking vulnerability in the AMD Cleanup Utility could allow an attacker to achieve privilege escalation potentially resulting in arbitrary code execution.

Improper isolation of VCN-JPEG HW register space could allow a malicious Guest Virtual Machine (VM) or a process to perform unauthorized access to the register space of the JPEG cores assigned a victim VM/process, potentially gaining arbitrary read/write access to the victim VM/process data.

Out of bounds write in AMD AMDGV_CMD_GET_DIAG_DATA ioctl handler could allow a local user to escalate privileges via remote code execution.

An unchecked return value within the AMD Platform Management Framework (PMF) could allow an attacker to write to an arbitrary memory address resulting in denial of service or arbitrary code execution.

Improper input validation within the AMD Platform Management Framework (PMF) could allow an attacker to unmap arbitrary memory pages potentially impacting integrity and availability, or allowing privilege escalation resulting in loss of confidentiality.

An out of bounds write within the AMD Platform Management Framework (PMF) could allow an attacker to execute arbitrary code at an elevated privilege level potentially leading to loss of confidentiality integrity, or availability.

An unchecked return value within the AMD Platform Management Framework (PMF) could allow an attacker to read or modify an arbitrary address potentially resulting in loss of confidentiality, integrity, or availability.

Improper Input Validation in the AMD RAID driver could allow an attacker to point to an arbitrary memory location potentially resulting in privilege escalation and arbitrary code execution.

Improper restriction of operations within the bounds of a memory buffer in the AMD secure processer (ASP) could allow an attacker to read or write to protected memory potentially resulting in arbitrary code execution.

Improperly preserved integrity of hardware configuration state during a power save/restore operation in the AMD Secure Processor (ASP) could allow an attacker with the ability to write outside the trusted memory range (TMR) to change the execution flow of the Video Core Next (VCN) firmware potentially impacting confidentiality, integrity, or availability.
