Description Alex 2023-02-15 17:20:32 UTC 
A Linux Kernel flaw integer overflow in the wireless RNDIS USB device driver found (actual for the Broadcom BCM4320 chip and maybe for other similar if any). A local user potentially can install such malicious USB device to trigger this, but unlikely that regular user if without admin or physical access can trigger this.
