      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ndax: read holder_ops once in dax_holder_notify_failure()\n\ndax_holder_notify_failure() reads dax_dev->holder_ops twice without\nREAD_ONCE() -- once for the NULL check and once for the indirect\nnotify_failure() call. A concurrent fs_put_dax() can clear holder_ops\nbetween the two reads, so the check can observe a non-NULL pointer while\nthe call dereferences NULL. (kill_dax() also clears holder_ops, but only\nafter synchronize_srcu(), so it cannot race a reader that is inside\ndax_read_lock(); fs_put_dax() does no such synchronization.)\n\nFetch holder_ops once into a local with READ_ONCE() so the NULL check and\nthe indirect call observe the same value.",
