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 during SMM.

Dell Inspiron 5675 BIOS versions prior to 1.4.1 contain a UEFI BIOS RuntimeServices overwrite vulnerability. A local attacker with access to system memory may exploit this vulnerability by overwriting the RuntimeServices structure to execute arbitrary code in System Management Mode (SMM).
