Dell BIOS contains a Stack based buffer overflow vulnerability. A local authenticated attacker could potentially exploit this vulnerability by using an SMI to send larger than expected input to a parameter to gain arbitrary code execution in SMRAM.

Dell BIOS contains a Time-of-check Time-of-use vulnerability. A local authenticated malicious user could\u00a0potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI to gain arbitrary code execution on the system.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with admin privileges may potentially exploit this vulnerability in order to modify a UEFI variable.

Dell BIOS contains a heap buffer overflow vulnerability. A local attacker with admin privileges could potentially exploit this vulnerability to perform an arbitrary write to SMRAM during SMM.

A buffer overflow in the WMI SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to execute arbitrary code.
