The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to drop meta_inode's page     cache in f2fs_put_super() syzbot reports a kernel bug as below: F2FS-fs (loop1): detect filesystem     reference count leak during umount, type: 10, count: 1 kernel BUG at fs/f2fs/super.c:1639!

The root case is,     during f2fs_put_super(), if there is any IO error in f2fs_wait_on_all_pages(), we missed to truncate     meta_inode's page cache later, result in panic, fix this case. (CVE-2023-52848)

Note that Nessus relies on the presence of the package as reported by the vendor.
