Dell BIOS versions contain a Stack-based Buffer Overflow vulnerability. A local authenticated malicious user could potentially exploit this vulnerability by sending excess data to a function in order to gain arbitrary code execution on the system.

Dell BIOS versions contain an Unchecked Return Value vulnerability. A local authenticated administrator user could potentially exploit this vulnerability in order to change the state of the system or cause unexpected failures.

Dell BIOS versions contain an Improper Protection Against Voltage and Clock Glitches vulnerability. An attacker with physical access to the system could potentially exploit this vulnerability by triggering a fault condition in order to change the behavior of the system.

Dell BIOS versions contain an Improper Neutralization of Null Byte vulnerability. A local authenticated administrator user could potentially exploit this vulnerability by sending unexpected null bytes in order to read memory on the system.

Dell BIOS versions contain a Missing Release of Resource after Effective Lifetime vulnerability. A local authenticated administrator user could potentially exploit this vulnerability by consuming excess memory in order to cause the application to crash.

Dell BIOS versions contain an Information Exposure vulnerability. A local authenticated administrator user could potentially exploit this vulnerability in order access sensitive state information on the system.

Dell BIOS versions contain an Unchecked Return Value vulnerability. A local authenticated administrator user could potentially exploit this vulnerability in order to change the state of the system or cause unexpected failures.

Select Dell Client Commercial and Consumer platforms are vulnerable to an insufficient verification of data authenticity vulnerability. An authenticated malicious user may exploit this vulnerability in order to install modified BIOS firmware.

Select Dell Client Commercial and Consumer platforms contain a pre-boot direct memory access (DMA) vulnerability. An authenticated attacker with physical access to the system may potentially exploit this vulnerability in order to execute arbitrary code on the device.

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.

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.

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 BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

Dell BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

Dell BIOSConnect feature contains a buffer overflow vulnerability. An authenticated malicious admin user with local access to the system may potentially exploit this vulnerability to run arbitrary code and bypass UEFI restrictions.

Dell UEFI BIOS https stack leveraged by the Dell BIOSConnect feature and Dell HTTPS Boot feature contains an improper certificate validation vulnerability. A remote unauthenticated attacker may exploit this vulnerability using a person-in-the-middle attack which may lead to a denial of service and payload tampering.

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.

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.

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. Refer to https://www.dell.com/support/article/us/en/04/sln317683/dsa-2019-043-dell-client-improper-access-control-vulnerability?lang=en for versions affected by this vulnerability.

Dell BIOS contains an Improper Input Validation vulnerability in an externally developed component. A high privileged attacker with local access could potentially exploit this vulnerability, leading to Code execution.
