In issue case, geni_wake pointer is initialized while UART probe and as a part of UART exit path wakeup_source_unregister is being called to free the geni_wake pointer from memory but still caller function can have the garbage value of geni_wake pointer which is being accessed in uart_remove_one_port and leading to UAF. To fix the issue we will make geni_wake pointer value as NULL after freeing it to from memory.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
