Use-After-Free Vulnerability in FreeRDP libusb_udev_select_interface

Publication date: 2026-02-09

Last updated on: 2026-02-10

Assigner: GitHub, Inc.

Description
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, urb_select_interface can free the device's MS config on error but later code still dereferences it, leading to a use after free in libusb_udev_select_interface. This vulnerability is fixed in 3.22.0.

CWE ID Description
CWE-416 The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Executive Summary

This vulnerability exists in FreeRDP, a free implementation of the Remote Desktop Protocol. Before version 3.22.0, the function urb_select_interface could free the device's MS configuration on error, but subsequent code would still attempt to access (dereference) this freed memory. This leads to a use-after-free condition in the libusb_udev_select_interface function, which can cause unexpected behavior or crashes. The issue was fixed in version 3.22.0.

Impact Analysis

A use-after-free vulnerability can lead to memory corruption, which attackers might exploit to execute arbitrary code, cause application crashes, or trigger denial of service conditions. Since this vulnerability occurs in FreeRDP, it could potentially allow remote attackers to compromise systems using vulnerable versions of FreeRDP by exploiting this flaw.
