Hi,

please backport commit fc4992458e0a ("fs/ntfs3: Add null pointer checks") to the 5.15 and 6.1 stable branches.

Commit message

""" Added null pointer checks in function ntfs_security_init. Also added le32_to_cpu in functions ntfs_security_init and indx_read. """

We are able to reproduce below Syzkaller report on these two stable builds. The issue does not reproduce on upstream, older, or newer LTS releases. Above patch fixes the issue.

Now queued up,t hanks.
