CVE-2022-26873

CVE-2022-26873 affects AMI Aptio 5.x PlatformInitAdvancedPreMem. The issue is described as a stack buffer overflow in PlatformInitAdvancedPreMem that can allow arbitrary code execution during the PEI phase, potentially enabling mitigation bypass, memory contents disclosure, VM secrets access, and...

CVE-2022-26873 The stack buffer overflow vulnerability in PlatformInitAdvancedPreMem leads to arbitrary code execution during PEI phase.

A potential attacker can execute an arbitrary code at the time of the PEI phase and influence the subsequent boot stages. This can lead to the mitigations bypassing, physical memory contents disclosure, discovery of any secrets from any Virtual Machines VMs and bypassing memory isolation and...
