Unsafe deserialization in Dell ControlVault3 cvhDecapsulateCmd
CVE-2025-24919 is an unsafe deserialization vulnerability in Dell ControlVault3 prior to 5.15.10.14 and ControlVault3 Plus prior to 6.2.26.36. The flaw exists in the host-side cvhDecapsulateCmd functionality used by ControlVault’s Windows APIs to process firmware-defined response data. A specially crafted ControlVault response to a command can be deserialized unsafely by bcmbipdll.dll, leading to memory corruption; the supporting research specifically states this host-side decapsulation path can cause a stack overflow in host processes. The issue is exploitable when an attacker can cause the host to consume a malicious response from compromised or attacker-controlled ControlVault firmware.
