# CVE-2026-25997: freerdp3: FreeRDP is a free implementation of the Remote Desktop Protocol CVE-2026-25997 is fixed in 27 products on 1 platform, first by freerdp3-proxy 3.16.0+dfsg-2ubuntu0.3, released February 25, 2026. It is not reported as exploited. Patch Radar priority: Urgent. - Web page: https://patchblox.com/security/cve/CVE-2026-25997 - Priority: Urgent - CVSS: 9.8 (critical) - EPSS: 0.0065 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Feb 25, 2026 ## Description FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, `xf_clipboard_format_equal` reads freed `lastSentFormats` memory because `xf_clipboard_formats_free` (called from the cliprdr channel thread during auto-reconnect) frees the array while the X11 event thread concurrently iterates it in `xf_clipboard_changed`, triggering a heap use after free. Version 3.23.0 fixes the issue. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | freerdp RHEL 10 | 3.10.3-3.el10_0.7 |
