## Overview

In the Linux kernel, the following vulnerability has been resolved:

fs/ntfs3: Fix memory leak on ntfs_fill_super() error path

syzbot reported kmemleak as below:

BUG: memory leak
unreferenced object 0xffff8880122f1540 (size 32):
  comm "a.out", pid 6664, jiffies 4294939771 (age 25.500s)
  hex dump (first 32 bytes):
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................
    00 00 00 00 00 00 00 00 ed ff ed ff 00 00 00 00  ................
  backtrace:
    [<ffffffff81b16052>] ntfs_init_fs_context+0x22/0x1c0
    [<ffffffff8164aaa7>] alloc_fs_context+0x217/0x430
    [<ffffffff81626dd4>] path_mount+0x704/0x1080

    [<ffffffff84600087>] entry_SYSCALL_64_after_hwframe+0x63/0xcd

This patch fixes this issue by freeing mount options on error path of
ntfs_fill_super().

## Affected

- `linux_kernel >= 5.15, < 5.15.87`
- `linux_kernel >= 5.16, < 6.0.17`
- `linux_kernel >= 6.1, < 6.1.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.1.3`
