-Subject: Bluetooth: Properly check L2CAP config option output buffer length
-
-From: Ben Seri <ben@armis.com>
-
-commit e860d2c904d1a9f38a24eb44c9f34b8f915a6ea3 upstream.
-
-Validate the output buffer length for L2CAP config requests and responses
-to avoid overflowing the stack buffer used for building the option blocks.
