  "description": "In the Linux kernel, the following vulnerability has been resolved:  f2fs: remove WARN_ON in f2fs_is_valid_blkaddr  Syzbot triggers two WARNs in f2fs_is_valid_blkaddr and __is_bitmap_valid. For example, in f2fs_is_valid_blkaddr, if type is DATA_GENERIC_ENHANCE or DATA_GENERIC_ENHANCE_READ, it invokes WARN_ON if blkaddr is not in the right range. The call trace is as follows:   f2fs_get_node_info\u002B0x45f/0x1070  read_node_page\u002B0x577/0x1190  __get_node_page.part.0\u002B0x9e/0x10e0  __get_node_page  f2fs_get_node_page\u002B0x109/0x180  do_read_inode  f2fs_iget\u002B0x2a5/0x58b0  f2fs_fill_super\u002B0x3b39/0x7ca0  Fix these two WARNs by replacing WARN_ON with dump_stack.",
