CVE-2026-109944

CVE-2026-109944 · FreeRDP 3.0.0 before 3.32.0 Reachable Assertion via Stale Smartcard Handle

This page contains facts from public vulnerability sources. Check the original advisory before updating.

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.
