Description OSIDB Bzimport 2026-10-14 23:02:22 UTC 
FreeRDP before 3.32.0 fails to close prior serial handles in serial_process_irp_create, allowing a malicious RDP server to exhaust file descriptors. Attackers can send repeated serial IRP_MJ_CREATE requests to accumulate descriptors and terminate the client at the CommReadFile FD_SETSIZE assertion.
