CVE-2026-25953 – FreeRDP has heap-use-after-free in xf_AppUpdateWindowFromSurface (freed appWindow)

CVE ID : CVE-2026-25953

Published : Feb. 25, 2026, 8:27 p.m. | 42 minutes ago

Description : FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_AppUpdateWindowFromSurface` reads from a freed `xfAppWindow` because the RDPGFX DVC thread obtains a bare pointer via `xf_rail_get_window` without any lifetime protection, while the main thread can concurrently delete the window through a fastpath window-delete order. Version 3.23.0 fixes the issue.

Severity: 0.0 | NA
