CVE-2026-121406

FreeRDP before 3.32.2 allows a client assertion abort because rdpgfxondatareceived rejects only negative zgfxdecompress status and passes the resulting null output pointer to StreamStaticConstInit. A malicious RDP server can send a zero-output ZGFX payload on the RDPGFX channel after session...

CVE-2026-121410

FreeRDP before 3.32.2 contains a denial of service vulnerability in the RDPGFX ALPHA WIRETOSURFACE2 handler that fails to validate zero surface dimensions. A malicious RDP server can send a crafted WIRETOSURFACE2 PDU with zero width and height, triggering an assertion or division by zero that...

CVE-2026-121402

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.
