Improper input validation in some Intel(R) Server Board BIOS firmware may allow a privileged user to potentially enable escalation of privilege via local access

Improper input validation in some Intel(R) Server board and Intel(R) Server System BIOS firmware may allow a privileged user to potentially enable escalation of privilege via local access.

Improper buffer restrictions in some Intel(R) Server Board M10JNP2SB BIOS firmware before version 7.219 may allow a privileged user to potentially enable escalation of privilege via local access.

Improper buffer restrictions in some Intel(R) Server Board BIOS firmware may allow a privileged user to potentially enable escalation of privilege via local access.

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 confidential computing boundaries. Additionally, an attacker can build a payload which can be injected into the SMRAM memory.
