  "description": "In the Linux kernel, the following vulnerability has been resolved:  f2fs: fix to do sanity check on inline_dots inode  As Wenqing reported in bugzilla:  https://bugzilla.kernel.org/show_bug.cgi?id=215765  It will cause a kernel panic with steps: - mkdir mnt - mount tmp40.img mnt - ls mnt  folio_mark_dirty\u002B0x33/0x50 f2fs_add_regular_entry\u002B0x541/0xad0 [f2fs] f2fs_add_dentry\u002B0x6c/0xb0 [f2fs] f2fs_do_add_link\u002B0x182/0x230 [f2fs] __recover_dot_dentries\u002B0x2d6/0x470 [f2fs] f2fs_lookup\u002B0x5af/0x6a0 [f2fs] __lookup_slow\u002B0xac/0x200 lookup_slow\u002B0x45/0x70 walk_component\u002B0x16c/0x250 path_lookupat\u002B0x8b/0x1f0 filename_lookup\u002B0xef/0x250 user_path_at_empty\u002B0x46/0x70 vfs_statx\u002B0x98/0x190 __do_sys_newlstat\u002B0x41/0x90 __x64_sys_newlstat\u002B0x1a/0x30 do_syscall_64\u002B0x37/0xb0 entry_SYSCALL_64_after_hwframe\u002B0x44/0xae  The root cause is for special file: e.g. character, block, fifo or socket file, f2fs doesn\u0027t assign address space operations pointer array for mapping-\u003Ea_ops field, so, in a fuzzed image, if inline_dots flag was tagged in special file, during lookup(), when f2fs runs into __recover_dot_dentries(), it will cause NULL pointer access once f2fs_add_regular_entry() calls a_ops-\u003Eset_dirty_page().",
