Stack-based buffer overflow in Dell ControlVault3 securebio_identify
CVE-2025-24922 is a stack-based buffer overflow in the securebio_identify functionality of Dell ControlVault3 firmware prior to 5.15.10.14 and Dell ControlVault3 Plus firmware prior to 6.2.26.36. According to the provided content, data from a property of a supplied cv_object is copied into a stack buffer named data2 without ensuring that the property length fits the destination buffer. A specially crafted malicious cv_object delivered through a ControlVault API call can therefore overflow the stack and corrupt adjacent memory. The issue affects the ControlVault firmware attack surface exposed through Dell/Broadcom host APIs and can be triggered by a local caller interacting with the device.
