  "description": "In the Linux kernel, the following vulnerability has been resolved:  IB/hfi1: Correctly move list in sc_disable()  Commit 13bac861952a (\u0022IB/hfi1: Fix abba locking issue with sc_disable()\u0022) incorrectly tries to move a list from one list head to another.  The result is a kernel crash.  The crash is triggered when a link goes down and there are waiters for a send to complete.  The following signature is seen:    BUG: kernel NULL pointer dereference, address: 0000000000000030   [...]   Call Trace:    sc_disable\u002B0x1ba/0x240 [hfi1]    pio_freeze\u002B0x3d/0x60 [hfi1]    handle_freeze\u002B0x27/0x1b0 [hfi1]    process_one_work\u002B0x1b0/0x380    ? process_one_work\u002B0x380/0x380    worker_thread\u002B0x30/0x360    ? process_one_work\u002B0x380/0x380    kthread\u002B0xd7/0x100    ? kthread_complete_and_exit\u002B0x20/0x20    ret_from_fork\u002B0x1f/0x30  The fix is to use the correct call to move the list.",
