CVE-2025-25050

Memory corruption via firmware-upgrade out-of-bounds write

Published Jun 13, 2025 · Updated Feb 26, 2026

Out-of-bounds write in Dell ControlVault3 and Plus allows local users to corrupt memory through a crafted firmware-upgrade API call. The cv_upgrade_sensor_firmware handler accepts a specially crafted ControlVault API request and writes beyond its intended buffer boundary. Local low-privilege access is required, and no user interaction is needed; the disclosed consequence is the out-of-bounds memory write.
