Dell Client Platform BIOS contains a Stack-based Buffer Overflow Vulnerability. A high privileged attacker with local access could potentially exploit this vulnerability, leading to arbitrary code execution.

Dell Edge Gateway BIOS, versions 3200 and 5200, contains an out-of-bounds write vulnerability. A local authenticated malicious user with high privileges could potentially exploit this vulnerability leading to exposure of some UEFI code, leading to arbitrary code execution or escalation of privilege.

Affected Dell Client platforms contain a BIOS Setup configuration authentication bypass vulnerability in the pre-boot Intel Rapid Storage Response Technology (iRST) Manager menu. An attacker with physical access to the system could perform unauthorized changes to the BIOS Setup configuration settings without requiring the BIOS Admin password by selecting the Optimized Defaults option in the pre-boot iRST Manager.
