Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
