Description Srikanth Balasubramanian 2026-10-26 14:37:05 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

FreeRDP 3.0.0 before 3.32.0 does not remove card handles when Emulate_SCardReleaseContext releases a smartcard-emulation context, so Emulate_SCardTransmit later looks up the deleted parent context and reaches a terminating WINPR_ASSERT. A malicious RDP server can crash a connecting client with smartcard emulation and redirection enabled by releasing a context, establishing another, and issuing SCardTransmit with the stale card handle.

This issue is fixed in FreeRDP 3.32.0. Fedora currently ships freerdp 3.32.2 in all supported branches (F43, F44, F45 and Rawhide), so this flaw is no longer present. Closing as ERRATA.
