Short explanation
FreeRDP versions from 3.0.0 up to but not including 3.32.0 contain a null‑pointer dereference in the smartcard emulation backend. A malicious RDP server can send a crafted SCardGetStatusChange request with a null szReader, causing the client process to crash. No confirmed patch is available in official sources.
Process crash can terminate RDP sessions, resulting in denial of service and degraded user experience.
What should be done?
- Upgrade to FreeRDP 3.32.0 or later
- Monitor vendor security advisories
- Disable smartcard redirection if not required
- Watch for future patches from the vendor
