CVE-2019-18579

Status: ModifiedMedium (6.8)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
