n the Linux kernel, the following vulnerability has been resolved: f2fs: fix to bail out in get_new_segment() ------------[ cut here ]------------ WARNING: CPU: 3 PID: 579 at fs/f2fs/segment.c:2832 new_curseg+0x5e8/0x6dc pc : new_curseg+0x5e8/0x6dc Call trace: new_curseg+0x5e8/0x6dc f2fs_allocate_data_block+0xa54/0xe28 do_write_page+0x6c/0x194 f2fs_do_write_node_page+0x38/0x78 __write_node_page+0x248/0x6d4 f2fs_sync_node_pages+0x524/0x72c f2fs_write_checkpoint+0x4bc/0x9b0 __checkpoint_and_complete_reqs+0x80/0x244 issue_checkpoint_thread+0x8c/0xec kthread+0x114/0x1bc ret_from_fork+0x10/0x20 get_new_segment() detects inconsistent status in between free_segmap and free_secmap, let's record such error into super block, and bail out get_new_segment() instead of continue using the segment.
