CVE-2026-109944 PUBLISHED

FreeRDP 3.0.0 before 3.32.0 Reachable Assertion via Stale Smartcard Handle

Assigner: VulnCheck
Reserved: 13.10.2026 Published: 13.10.2026 Updated: 13.10.2026

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.
