Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by using an SMI to gain arbitrary code execution in SMRAM.

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.

Dell BIOS contains an information exposure vulnerability. An unauthenticated local attacker with physical access to the system and knowledge of the system configuration could potentially exploit this vulnerability to read system information via debug interfaces.

Dell Client Consumer and Commercial platforms include an improper authorization vulnerability in the Dell Manageability interface for which an unauthorized actor, with local system access with OS administrator privileges, could bypass the BIOS Administrator authentication to restore BIOS Setup configuration to default values.

Select Dell Client Commercial and Consumer platforms contain an Improper Access Vulnerability. An unauthenticated attacker with physical access to the system could potentially bypass intended Secure Boot restrictions to run unsigned and untrusted code on expansion cards installed in the system during platform boot.
