Description OSIDB Bzimport 2025-12-16 16:04:32 UTC 
In the Linux kernel, the following vulnerability has been resolved:

f2fs: fix to detect potential corrupted nid in free_nid_list

As reported, on-disk footer.ino and footer.nid is the same and
out-of-range, let's add sanity check on f2fs_alloc_nid() to detect
any potential corruption in free_nid_list.
