Executive Summary

This vulnerability exists in certain Ampere AmpereOne devices where an incorrectly formed SMC (Secure Monitor Call) to the UEFI-MM PCIe driver can cause an out-of-bounds write within the PCIe driver's S-EL0 address space. This means that improper input to the PCIe driver can lead to memory corruption.

Impact Analysis

The vulnerability could lead to memory corruption in the PCIe driver, which may result in system instability, crashes, or potentially allow an attacker to execute arbitrary code or escalate privileges on affected devices.
