CVE-2026-44422

CVE-2026-44422 affects FreeRDP prior to 3.26.0. The RDPEAR NDR parser incorrectly reused a non-null NDR pointer ref-id across multiple logical pointer fields, causing the same heap object to be assigned to two outputs. The destructor then frees both pointers, enabling a heap use-after-free / doub...
