ghes_handle_aer() passes AER data to the PCI core for logging and recovery by calling aer_recover_queue() with a pointer to struct aer_capability_regs. The problem was that aer_recover_queue() queues the pointer directly without copying the aer_capability_regs data. The pointer was to the ghes->estatus buffer, which could be reused before aer_recover_work_func() reads the data. To avoid this problem, allocate a new aer_capability_regs structure from the ghes_estatus_pool, copy the AER data from the ghes->estatus buffer into it, pass a pointer to the new struct to aer_recover_queue(), and free it after aer_recover_work_func() has processed it.

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.
