Last modified

CVE-2026-110831 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. FreeRDP versions 3.13.0 before 3.32.0 contain a resource retention flaw in drive_process_irp_create, which registers an opened local file in the drive dictionary before applying the allocation size and does not remove it when that operation fails. A malicious RDP server connected to a client with drive redirection enabled can send IRP_MJ_CREATE with AllocationSize set to UINT64_MAX, forcing the seek to fail and leaking the file object and operating-system handle until drive teardown.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
