CVE-2024-39467

CVE-2024-39467 (Linux kernel, f2fs) is rooted in a missing sanity check for i_xattr_nid in f2fs_iget(). In the fiemap path this allows current_nat_addr() to read from nat_bitmap using an invalid i_xattr_nid, triggering a KASAN slab-out-of-bounds bug. The issue is fixed by adding the sanity check ...
