Use-After-Free Vulnerability in FreeRDP SDL Pointer Component

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, sdl_Pointer_New frees data on failure, then pointer_free calls sdl_Pointer_Free and frees it again, triggering ASan UAF. 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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

The vulnerability exists in FreeRDP, a free implementation of the Remote Desktop Protocol. Before version 3.22.0, there is a flaw in the sdl_Pointer_New function where it frees data on failure, and then pointer_free calls sdl_Pointer_Free which frees the same data again. This double free leads to a Use-After-Free (UAF) condition detected by AddressSanitizer (ASan).

Impact Analysis

This vulnerability can lead to a Use-After-Free condition, which may allow an attacker to execute arbitrary code, cause a crash, or trigger undefined behavior in the affected software. Since FreeRDP is used for remote desktop connections, exploitation could compromise the security and stability of remote sessions.
