Summary
Dell PowerEdge R640, R740, R740XD, R840, R940, R940xa, MX740c, MX840c, and, Dell Precision 7920 Rack Workstation BIOS contain a stack-based buffer overflow vulnerability in systems with Intel Optane DC Persistent Memory installed. A local malicious user with high privileges may potentially exploit this vulnerability, leading to a denial of Service, arbitrary code execution, or information disclosure in UEFI or BIOS Preboot Environment.
