In the Linux kernel, the following vulnerability has been resolved: block: integrity: Do not call setpagedirtylock() Placing multiple protection information buffers inside the same page can lead to oopses because setpagedirtylock() can't be called from interrupt context. Since a protection information buffer is not backed by a file there is no point in setting its page dirty, there is nothing to synchronize. Drop the call to setpagedirtylock() and remove the last argument to biointegrityunpinbvec().
