| CVE-2026-22857 | Cri | 0.64 | 9.8 | 0.01 | Jan 14, 2026 | FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a heap use-after-free occurs in irp_thread_func because the IRP is freed by irp->Complete() and then accessed again on the error path. This vulnerability is fixed in 3.20.1. | ||
