CVE-2026-22859

Exploit

FreeRDP has a heap-buffer-overflow in urb_select_configuration

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, the URBDRC client does not perform bounds checking on server‑supplied MSUSB_INTERFACE_DESCRIPTOR values and uses them as indices in libusb_udev_complete_msconfig_setup, causing an out‑of‑bounds read. This vulnerability is fixed in 3.20.1.
