Summary
Settings for the Dell XPS 13 2-in-1 (7390) BIOS versions prior to 1.1.3 contain a configuration vulnerability. The BIOS configuration for the "Enable Thunderbolt (and PCIe behind TBT) pre-boot modules" setting is enabled by default. A local unauthenticated attacker with physical access to a user's system can obtain read or write access to main memory via a DMA attack during platform boot.
