    CVE-2026-114042

    FreeRDP 3.32.0 contains a use-after-free vulnerability in the drdynvc channel that frees a pool-owned stream with the owned-stream deallocator when totalLength is smaller than the chunk size. A malicious RDP server can send a single well-formed Virtual Channel PDU to trigger the free and crash the client during teardown.
