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 3 (`WBIO_USH_CREATE_CHALLENGE`) with an invalid `ReceiveBuferSize`.
