CVE-2015-2890 is a medium-severity vulnerability rated 6/10 on the CVSS scale. The BIOS implementation on Dell Latitude, OptiPlex, Precision Mobile Workstation, and Precision Workstation Client Solutions (CS) devices with model-dependent firmware before A21 does not enforce a BIOS_CNTL locking protection mechanism upon being woken from sleep, which allows local users to conduct EFI flash attacks by leveraging console access, a similar issue to CVE-2015-3692.. EPSS estimates a 0.77% chance of exploitation in the next 30 days.
