CVE-2022-34393

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.

CVE-2020-5378

Dell G7 17 7790 BIOS versions prior to 1.13.2 contain a UEFI BIOS Boot Services overwrite vulnerability. A local attacker with access to system memory may exploit this vulnerability by overwriting the EFI_BOOT_SERVICES structure to execute arbitrary code in System Management Mode (SMM).

CVE-2020-5387

Dell XPS 13 9370 BIOS versions prior to 1.13.1 contains an Improper Exception Handling vulnerability. A local attacker with physical access could exploit this vulnerability to prevent the system from booting until the exploited boot device is removed.

CVE-2021-36284

Dell BIOS contains an Improper Restriction of Excessive Authentication Attempts vulnerability. A local authenticated malicious administrator could exploit this vulnerability to bypass excessive admin password attempt mitigations in order to carry out a brute force attack.

CVE-2021-36285

Dell BIOS contains an Improper Restriction of Excessive Authentication Attempts vulnerability. A local authenticated malicious administrator could exploit this vulnerability to bypass excessive NVMe password attempt mitigations in order to carry out a brute force attack.

CVE-2022-34403

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.

CVE-2020-5388

Dell Inspiron 15 7579 2-in-1 BIOS versions prior to 1.31.0 contain an Improper SMM communication buffer verification vulnerability. A local authenticated malicious user may potentially exploit this vulnerability by using an SMI to gain arbitrary code execution in SMRAM.
