CVE-2026-121402

FreeRDP before 3.32.2 X11 Client Crash via Zero-Width RDPGFX ResetGraphics

Published Nov 3, 2026 CVSS 4.0 · 7.1 High EPSS < 1% KEV · Not listed
Description
FreeRDP before 3.32.2 contains a NULL pointer dereference vulnerability that allows malicious RDP servers to crash xfreerdp clients by sending a zero-width RDPGFX ResetGraphics PDU. The failed resize in gdi_resize_ex leaves the primary display null without ending the session, so a later bitmap update crashes the client in gdi_Bitmap_Paint.
