NewCVE-2026-67304 (opens in a new tab)How to fix?
Upgrade freerdp/freerdp to version 3.29.0 or higher.
Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference in the free_reader_states process. An attacker can cause the application to crash by sending specially crafted smartcard IRP requests that trigger a null pointer dereference during cleanup. This is only exploitable if smartcard redirection is enabled.
Workaround
This vulnerability can be mitigated by disabling smartcard redirection in client configurations, such as launching the client without the /smartcard option or explicitly setting /smartcard:no.
