EDK2 contains a vulnerability in BIOS where an attacker may cause “ Improper Input Validation” by local access. Successful exploitation of this vulnerability could alter control flow in unexpected ways, potentially allowing arbitrary command execution and impacting Confidentiality, Integrity, and Availability.

EDK2 contains a vulnerability in BIOS where an attacker may cause “Exposure of Sensitive Information to an Unauthorized Actor” by local access. Successful exploitation of this vulnerability will lead to possible information disclosure or escalation of privilege and impact Confidentiality.

EDK2 contains a vulnerability in the PeCoffLoaderRelocateImage(). An Attacker may cause memory corruption due to an overflow via an adjacent network. A successful exploit of this vulnerability may lead to a loss of Confidentiality, Integrity, and/or Availability.

EDK2 contains a vulnerability when S3 sleep is activated where an Attacker may cause a Division-By-Zero due to a UNIT32 overflow via local access. A successful exploit of this vulnerability may lead to a loss of Availability.
