Summary
Realtek NDIS driver rt640x64.sys, file version 10.1.505.2015, fails to do any size checking on an input buffer from user space, which the driver assumes has a size greater than zero bytes. To exploit this vulnerability, an attacker must send an IRP with a system buffer size of 0.
Exploit prediction
0.28% chance of exploitation in the next 30 days, higher than 21% of all scored CVEs (FIRST EPSS, 2026-11-08).
