- CVE-2026-91953, CVE-2026-91964: bound every write in nego_send_negotiation_request() with Stream_EnsureRemainingCapacity(); the routing token taken from the server's LB_LOAD_BALANCE_INFO was written into a fixed 512 byte stream unchecked, overflowing the heap allocation - CVE-2026-91963: allocate wStream buffers with calloc() instead of malloc(), so the urbdrc completion path can no longer return the untouched tail of a freshly allocated buffer - and with it live heap pointers - to the server when a USB transfer returns short - CVE-2026-91959: require four remaining bytes in rts_read_result() before reading result and reason; a malicious RD Gateway could end a BIND_ACK fragment two bytes into a result and make the parser over-read it - CVE-2026-91957: do not free the SMARTCARD_DEVICE on the DeviceServiceEntry() failure path once RegisterDevice() has succeeded; devman kept the freed pointer and dereferenced DEVICE.Free through it on channel teardown - CVE-2026-91956: bound the interface, alternate-setting and endpoint indices in func_get_ep_desc(); it indexed by array position while the validator indexed by InterfaceNumber, so a permuted descriptor produced an out-of-bounds read of a pointer that was then dereferenced
