CVE-2025-24919

Arbitrary code execution via unchecked firmware response parameters

Published Jun 13, 2025 · Updated Feb 26, 2026

Deserialization in Dell ControlVault3 before 5.15.10.14 and ControlVault3 Plus before 6.2.26.36 allows attackers to execute arbitrary code. cvhDecapsulateCmd trusts firmware-supplied parameter types, lengths, and counts instead of the expected parameter list, enabling out-of-bounds writes. Exploitation requires compromised BCM5820X firmware or a malicious USB device masquerading as ControlVault, and code runs in the calling process.
