CVE-2022-50715
Estado: AplazadaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
md/raid1: stop mdx_raid1 thread when raid1 array run failed
fail run raid1 array when we assemble array with the inactive disk only, but the mdx_raid1 thread were not stop, Even if the associated resources have been released. it will caused a NULL dereference when we do poweroff.
In fact, when raid1 array run fail, we need to do md_unregister_thread() before raid1_free().
