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

net: wwan: t7xx: Fix FSM command timeout issue

When driver processes the internal state change command, it use an
asynchronous thread to process the command operation. If the main
thread detects that the task has timed out, the asynchronous thread
will panic when executing the completion notification because the
main thread completion object has been released.
