CVE-2022-48947 at MITRE

Description

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: L2CAP: Fix u8 overflow

By keep sending L2CAP_CONF_REQ packets, chan->num_conf_rsp increases
multiple times and eventually it will wrap around the maximum number
(i.e., 255).
This patch prevents this by adding a boundary check with
L2CAP_MAX_CONF_RSP
