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

• Severity: medium (CVSS 6.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-10-13 · updated 2026-10-26
• Weakness: CWE-617

Description

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.

• FreeRDP: from 3.0.0 before 3.32.0 — fixed in 3.32.0
• FreeRDP: from 3.0.0 before 3.32.0 — fixed in 3.32.0

How to fix

Upgrade to a fixed version: FreeRDP 3.32.0; FreeRDP 3.32.0. Check the vendor advisory for mitigations.
