CVE-2026-109947 · FreeRDP 3.20.1 before 3.32.0 Unbounded Allocation via drive_process_irp_read

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

FreeRDP from 3.20.1 before 3.32.0 contains an uncontrolled resource allocation vulnerability that allows malicious RDP servers to exhaust client memory via oversized drive redirection read requests. Attackers can send IRP_MJ_READ with Length 0xffffffff, causing roughly 4 GiB of zeroed allocation on 64-bit builds or an under-reserved buffer on 32-bit builds.
