    CVE-2026-121403

    Summary:

    Details: FreeRDP before 3.32.2 contains a denial of service vulnerability where a malformed drive DEVICE_IOREQUEST with a truncated IRP_MJ_CREATE body silently kills the drive worker. A malicious RDP server can send such an IRP then post further requests that accumulate unbounded in the IrpQueue, exhausting memory and causing session availability loss.
