Оригинално описание
In the Linux kernel, the following vulnerability has been resolved: dax: read holder_ops once in dax_holder_notify_failure() dax_holder_notify_failure() reads dax_dev->holder_ops twice without READ_ONCE() -- once for the NULL check and once for the indirect notify_failure() call. A concurrent fs_put_dax() can clear holder_ops between the two reads, so the check can observe a non-NULL pointer while the call dereferences NULL. (kill_dax() also clears holder_ops, but only after synchronize_srcu(), so it cannot race a reader that is inside dax_read_lock(); fs_put_dax() does no such synchronization.) Fetch holder_ops once into a local with READ_ONCE() so the NULL check and the indirect call observe the same value.
