Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Fix use after free on unload
System crash is observed with stack trace warning of use after
free. There are 2 signals to tell dpc_thread to terminate (UNLOADING
flag and kthread_stop).
On setting the UNLOADING flag when dpc_thread happens to run at the time
and sees the flag, this causes dpc_thread to exit and clean up
itself. When kthread_stop is called for final cleanup, this causes use
after free.
Remove UNLOADING signal to terminate dpc_thread. Use the kthread_stop
as the main signal to exit dpc_thread.
