    Added Description In the Linux kernel, the following vulnerability has been resolved:

    pds_core: make wait_context part of q_info

    Make the wait_context a full part of the q_info struct rather
    than a stack variable that goes away after pdsc_adminq_post()
    is done so that the context is still available after the wait
    loop has given up.

    There was a case where a slow development firmware caused
    the adminq request to time out, but then later the FW finally
    finished the request and sent the interrupt. The handler tried
    to complete_all() the completion context that had been created
    on the stack in pdsc_adminq_post() but no longer existed.
    This caused bad pointer usage, kernel crashes, and much wailing
    and gnashing of teeth.
