Please refer to https://learn.microsoft.com/en-us/windows/win32/secauthz/appcontainer-isolation and https://learn.microsoft.com/en-us/windows/win32/secauthz/mandatory-integrity-control

**What privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain specific limited SYSTEM privileges.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by tricking an authenticated user into opening a malicious MDB file in Access via ODBC, which could result in the attacker being able to execute arbitrary code on the victim's machine with the permission level at which Access is running.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by tricking an authenticated user into attempting to connect to a malicious SQL server via OLEDB, which could result in the server receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** This vulnerability could lead to a contained execution environment escape.

Azure RTOS USBx is a USB host, device, and on-the-go (OTG) embedded stack, fully integrated with Azure RTOS ThreadX and available for all Azure RTOS ThreadX–supported processors. Azure RTOS USBX implementation of host support for USB CDC ECM includes an integer underflow and a buffer overflow in the `_ux_host_class_cdc_ecm_mac_address_get` function which may be potentially exploited to achieve remote code execution or denial of service. Setting mac address string descriptor length to a `0` or `1` allows an attacker to introduce an integer underflow followed (string_length) by a buffer overflow of the `cdc_ecm -> ux_host_class_cdc_ecm_node_id` array. This may allow one to redirect the code execution flow or introduce a denial of service. The fix has been included in USBX release [6.1.12](https://github.com/azure-rtos/usbx/releases/tag/v6.1.12_rel). Improved mac address string descriptor length validation to check for unexpectedly small values may be used as a workaround.
