The ath11k driver is caching the information about RSN/WPA IE in the
configured beacon template. The cached information is used during
associations to figure out whether 4-way PKT/2-way GTK peer flags need to
be set or not.
But the code never cleared the state when no such IE was found. This can
for example happen when moving from an WPA/RSN to an open setup. The
(seemingly connected) peer was then not able to communicate over the
link because the firmware assumed a different (encryption enabled) state
for the peer.

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.
