CVE-2026-25954 – FreeRDP has heap-use-after-free in xf_rail_server_local_move_size

CVE ID : CVE-2026-25954

Published : Feb. 25, 2026, 8:30 p.m. | 38 minutes ago

Description : FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_rail_server_local_move_size` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` returns an unprotected pointer from the `railWindows` hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue.

Severity: 0.0 | NA
