Description SMASH SMASH 2024-07-09 08:42:10 UTC

tap-windows6 driver version 9.26 and earlier does not properly 
check the size data of incomming write operations which an attacker can 
use to overflow memory buffers, resulting in a bug check and potentially
 arbitrary code execution in kernel space
