{"id":"DEBIAN-CVE-2024-53220","details":"In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix to account dirty data in __get_secs_required()  It will trigger system panic w/ testcase in [1]:  ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.c:2752! RIP: 0010:new_curseg+0xc81/0x2110 Call Trace:  f2fs_allocate_data_block+0x1c91/0x4540  do_write_page+0x163/0xdf0  f2fs_outplace_write_data+0x1aa/0x340  f2fs_do_write_data_page+0x797/0x2280  f2fs_write_single_data_page+0x16cd/0x2190  f2fs_write_cache_pages+0x994/0x1c80  f2fs_write_data_pages+0x9cc/0xea0  do_writepages+0x194/0x7a0  filemap_fdatawrite_wbc+0x12b/0x1a0  __filemap_fdatawrite_range+0xbb/0xf0  file_write_and_wait_range+0xa1/0x110  f2fs_do_sync_file+0x26f/0x1c50  f2fs_sync_file+0x12b/0x1d0  vfs_fsync_range+0xfa/0x230  do_fsync+0x3d/0x80  __x64_sys_fsync+0x37/0x50  x64_sys_call+0x1e88/0x20d0  do_syscall_64+0x4b/0x110  entry_SYSCALL_64_after_hwframe+0x76/0x7e  The root cause is if checkpoint_disabling and lfs_mode are both on, it will trigger OPU for all overwritten data, it may cost more free segment than expected, so f2fs must account those data correctly to calculate cosumed free segments later, and return ENOSPC earlier to avoid run out of free segment during block allocation.
