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

f2fs: fix null-ptr-deref in f2fs_submit_page_bio()

There's issue as follows when concurrently installing the f2fs.ko
module and mounting the f2fs file system:
KASAN: null-ptr-deref in range [0x0000000000000020-0x0000000000000027]
RIP: 0010:__bio_alloc+0x2fb/0x6c0 [f2fs]

entry_SYSCALL_64_after_hwframe+0x76/0x7e

Above issue happens as the biset of the f2fs file system is not
initialized before register 'f2fs_fs_type'.
To address above issue just register 'f2fs_fs_type' at the last in
init_f2fs_fs(). Ensure that all f2fs file system resources are
initialized.
