NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-rt-64k-modules-partner package and not the kernel-rt-64k-modules-partner package as distributed by Centos.
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.
