Title
cifs: remove all cifs files before kill super
Summary
In the Linux kernel, the following vulnerability has been resolved: cifs: remove all cifs files before kill super Cifs files may be put into fileinfo_put_wq during umounting cifs. After umount done, cifsFileInfo_put_final is called, which cause following BUG: BUG: kernel NULL pointer dereference, address: 0000000000000000 ...
