Summary

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to don't dirty inode for readonly filesystem syzbot reports f2fs bug as below: kernel BUG at fs/f2fs/inode.c:933! RIP: 0010:f2fs_evict_inode+0x1576/0x1590 fs/f2fs/inode.c:933 Call Trace: evict+0x2a4/0x620 fs/inode.c:664 dispose_list fs/inode.c:697 [inline] evict_inodes+0x5f8/0x690 fs/inode.c:747 generic_shutdown_super+0x9d/0x2c0 fs/super.c:675 kill_block_super+0x44/0x90 fs/super.c:1667 kill_f2fs_super+0x303/0x3b0 fs/f2fs/super.c:4894 deactivate_locked_super+0xc1/0x130 fs/super.c:484 cleanup_mnt+0x426/0x4c0 fs/namespace.c:1256 task_work_run+0x24a/0x300 kernel/task_work.c:180 ptrace_notify+0x2cd/0x380 kernel/signal.c:2399 ptrace_report_syscall include/linux/ptrace.h:411 [inline] ptrace_report_syscall_exit include/linux/ptrace.h:473 [inline] syscall_exit_work kernel/entry/common.c:251 [inline] syscall_exit_to_user_mode_prepare kernel/entry/common.c:278 [inline] __syscall_exit_to_user_mode_work kernel/entry/common.c:283 [inline] syscall_exit_to_user_mode+0x15c/0x280 kernel/entry/common.c:296 do_syscall_64+0x50/0x110 arch/x86/entry/common.c:88 entry_SYSCALL_64_after_hwframe+0x63/0x6b The root cause is: - do_sys_open - f2fs_lookup - __f2fs_find_entry - f2fs_i_depth_write - f2fs_mark_inode_dirty_sync - f2fs_dirty_inode - set_inode_flag(inode, FI_DIRTY_INODE) - umount - kill_f2fs_super - kill_block_super - generic_shutdown_super - sync_filesystem : sb is readonly, skip sync_filesystem() - evict_inodes - iput - f2fs_evict_inode - f2fs_bug_on(sbi, is_inode_flag_set(inode, FI_DIRTY_INODE)) : trigger kernel panic When we try to repair i_current_depth in readonly filesystem, let's skip dirty inode to avoid panic in later f2fs_evict_inode().

There is no network-facing path into fs/f2fs/inode.c.\nAC:L - The trigger is fully deterministic with no race: one dirtying operation on a read-only f2fs mount guarantees FI_DIRTY_INODE survives to f2fs_evict_inode, since sync_filesystem() is unconditionally skipped for read-only superblocks. CONFIG_F2FS_CHECK_FS turns it into a hard BUG(), but the defect is not conditional on it \u2014 default configs still WARN and free the inode with a dangling sbi-\u003einode_list[DIRTY_META] entry.\nPR:L - An unprivileged local user with only read access to a file on a read-only f2fs mount can dirty the inode; f2fs_ioc_precache_extents() and f2fs_file_fadvise() perform no capability, ownership, or mnt_want_write check, and the __f2fs_find_entry depth-repair path needs nothing beyond stat(). Read-only f2fs volumes are routine on Android and embedded systems where any app can reach them.\nUI:N - The attacker performs the entire dirtying step alone; the eviction that fires the assertion happens during ordinary automatic system activity \u2014 volume unmount by vold/udisks2, media eject, or shutdown \u2014 rather than requiring a victim to be tricked into any action. On desktops where udisks2 permits console-user mount/unmount of removable media, the attacker controls the whole chain unaided.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - In default configurations f2fs_bug_on degrades to WARN_ON, so execution continues and f2fs_free_inode() releases the 1200-byte f2fs_inode_info while fi-\u003egdirty_list is still linked into sbi-\u003einode_list[DIRTY_META]; subsequent traversal of that list (f2fs_sync_inode_meta) reads through the freed, sprayable slab object. This is the same stale-gdirty_list use-after-free syzbot reported at this assertion site.\nI:H - The dangling DIRTY_META list node gives a write primitive \u2014 the next f2fs_inode_dirtied(sync=true) performs list_add_tail(), whose __list_add() writes a kernel pointer through head-\u003eprev into the freed and potentially reallocated f2fs_inode_cache object. Heap-sprayable slab corruption of this kind is exploitable for control-flow hijacking.\nA:H - With CONFIG_F2FS_CHECK_FS the f2fs_bug_on at fs/f2fs/inode.c:933 is a BUG_ON that panics the kernel mid-unmount, exactly as syzbot reported; without it the WARN_ON still panics under panic_on_warn and leaves the filesystem flagged SBI_NEED_FSCK. Either way the result is a full denial of service."
