Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0,     `xf_SetWindowMinMaxInfo` dereferences a freed `xfAppWindow` pointer because `xf_rail_get_window` in     `xf_rail_server_min_max_info` 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. (CVE-2026-25952)

Note that Nessus relies on the presence of the package as reported by the vendor.
