DEBIAN-CVE-2026-25997
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xfclipboardformat_equal reads freed lastSentFormats memory because xfclipboardformats_free (called from the cliprdr channel thread during auto-reconnect) frees the array while the X11 event thread concurrently iterates it in xfclipboardchanged, triggering a heap use after free. Version 3.23.0 fixes the issue.
