CVE-2015-2890: The BIOS implementation on Dell Latitude, OptiPlex, Precision Mobile Workstation, and Precision Workstation...

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.

Security readout for executives and security teams

This is a firmware weakness in certain Dell Latitude, OptiPlex, Precision Mobile Workstation, and Precision Workstation systems. After waking from sleep, BIOS write protections may not be enforced, allowing a local user with console access to attempt unauthorized EFI firmware modification. The main concern is persistent device compromise on older Dell endpoints. Exposure is most likely on legacy Dell Latitude, OptiPlex, Precision Mobile Workstation, and Precision Workstation devices still running BIOS firmware before the applicable fixed release, described as model-dependent and before A21. Systems allowing sleep/resume and local console access are most relevant. Treat this as a legacy endpoint firmware hygiene issue with potentially serious persistence impact but limited local-access prerequisites. Prioritize systems in shared, high-risk, regulated, or administrator-use environments, especially where BIOS updates have lagged. Mitigation focus: Check Dell and CERT guidance for the exact affected models and fixed BIOS versions.; Update affected Dell BIOS firmware to the applicable vendor-fixed release.; Restrict physical and console access to affected endpoints..
