CVE-2026-121402 Details
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.
