[ Upstream commitfb048cae51] All accesses (both reads and modifications) to hdev->{accept,reject}_list are protected by hdev lock, except the ones in hci_conn_request_evt. This can cause a race condition in the form of a list corruption. The solution is to protect these lists in hci_conn_request_evt as well. I was unable to find the exact commit that introduced the issue for the reject list, I was only able to find it for the accept list.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
