Out-of-bounds read in Dell ControlVault3 cv_send_blockdata

IdentifiersCVE-2025-24311CWE-125· Out-of-bounds Read

CVE-2025-24311 is an out-of-bounds read vulnerability in Dell ControlVault3 firmware prior to 5.15.10.14 and Dell ControlVault3 Plus firmware prior to 6.2.26.36. The flaw is in the cv_send_blockdata functionality. According to the provided content, a specially crafted ControlVault API call can trigger the vulnerable code path and cause the firmware to read memory outside the intended bounds, resulting in an information leak. The issue is part of the broader ReVault research into Dell ControlVault3 firmware and host interaction surfaces.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can disclose memory contents from the ControlVault firmware context. The primary direct impact described in the content is information leakage. Given the role of ControlVault3 as a hardware security component for credentials, biometric templates, and related security material, such leakage could expose sensitive firmware-resident data and aid further exploitation, although the provided content specifically characterizes this CVE as an information leak rather than code execution by itself.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure by limiting access to ControlVault APIs and the associated device interfaces to only trusted local users and processes, disabling unused ControlVault-related functionality or services where operationally feasible, and monitoring for abnormal access to ControlVault components and related service crashes. In higher-risk environments, consider disabling unused biometric, smart card, or NFC features that depend on ControlVault until updates can be applied.

Remediation

Patch, then assume compromise.

Upgrade Dell ControlVault3 to version 5.15.10.14 or later and Dell ControlVault3 Plus to version 6.2.26.36 or later. Apply Dell-provided firmware updates through the vendor’s normal update channels, including Windows Update or Dell firmware releases where applicable.
