 0033:0x7f238798cde9 index 18446744073709550692 (decimal, unsigned long long) = 0xfffffffffffffc64
 (hexadecimal, unsigned long long) = -924 (decimal, long long) In f2fs_truncate_inode_blocks(), UBSAN
 detects that get_nid() tries to access .i_nid[-924], it means both offset[0] and level should zero. The
 possible case should be in f2fs_do_truncate_blocks(), we try to truncate inode size to zero, however,
 dn.ofs_in_node is zero and dn.node_page is not an inode page, so it fails to truncate inode page, and then
 pass zeroed free_from to f2fs_truncate_inode_blocks(), result in this issue. if (dn.ofs_in_node ||
 IS_INODE(dn.node_page)) { f2fs_truncate_data_blocks_range(&dn, count); free_from += count; } I guess the
 reason why dn.node_page is not an inode page could be: there are multiple nat entries share the same node
 block address, once the node block address was reused, f2fs_get_node_page() may load a non-inode block.
 Let's add a sanity check for such condition to avoid out-of-bounds access issue. (CVE-2025-37739)

Solution

Update the linux library and its related packages to version 6.1.135-1 or later.
