GHSA-9h8x-5g7f-6f2f: 
In the Linux kernel, the following vulnerability has been resolved:fs/ntfs3: Add null pointer check for inode operationsThis adds a sanity check for the i_op pointer of the inode which is
returned after reading Root directory MFT record. We should check the
i_op is valid before trying to create the root dentry, otherwise we may
encounter a NPD while mounting a image with a funny Root directory MFT
record.[  114.484325] BUG: kernel NULL pointer dereference, address: 0000000000000008
