In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix null-ptr-deref of mreplace in raid10_sync_request There are two check of mreplace in raid10_sync_request(). In the first check, need_replace will be set and mreplace will be used later if no-Faulty mreplace exists, In the second check, mreplace will be set to NULL if it is Faulty, but need_replace will not be changed accordingly. null-ptr-deref occurs if Faulty is set between two check. Fix it by merging two checks into one. And replace need_replace with mreplace because their values are always the same.
