CVE-2026-67296 FreeRDP before 3.29.0 Denial of Service via RDPEI PDU

FreeRDP before 3.29.0 contains a denial of service vulnerability in the RDPEI server channel handler that fails to validate maximum PDU body length before stream allocation. A malicious RDP client can send a header-only RDPEI message with a large declared body length to force excessive memory...

CVE-2026-67296

CVE-2026-67296 affects FreeRDP prior to 3.29.0, where the RDPEI server channel handler may allocate excessive memory if a header-only RDPEI message declares a large body length, enabling a denial-of-service. This is documented in the NVD/CVE entries and CVE listing; no patch details are provided ...
