Title

ubifs: authentication: Fix use-after-free in ubifs_tnc_end_commit

Summary

In the Linux kernel, the following vulnerability has been resolved: ubifs: authentication: Fix use-after-free in ubifs_tnc_end_commit After an insertion in TNC, the tree might split and cause a node to change its `znode->parent`. A further deletion of other nodes in the tree (which also could free the nodes), the aforementioned node's `znode->cparent` could still point to a freed node. This `znode->cparent` may not be updated when getting nodes to commit in `ubifs_tnc_start_commit()`. This could then trigger a use-after-free when accessing the `znode->cparent` in `write_index()` in `ubifs_tnc_end_commit()`. This can be triggered by running rm -f /etc/test-file.bin dd if=/dev/urandom of=/etc/test-file.bin bs=1M count=60 conv=fsync in a loop, and with `CONFIG_UBIFS_FS_AUTHENTICATION`. KASAN then reports: BUG: KASAN: use-after-free in ubifs_tnc_end_commit+0xa5c/0x1950 Write of size 32 at addr ffffff800a3af86c by task ubifs_bgt0_20/153 Call trace: dump_backtrace+0x0/0x340 show_stack+0x18/0x24 dump_stack_lvl+0x9c/0xbc print_address_description.constprop.0+0x74/0x2b0 kasan_report+0x1d8/0x1f0 kasan_check_range+0xf8/0x1a0 memcpy+0x84/0xf4 ubifs_tnc_end_commit+0xa5c/0x1950 do_commit+0x4e0/0x1340 ubifs_bg_thread+0x234/0x2e0 kthread+0x36c/0x410 ret_from_fork+0x10/0x20 Allocated by task 401: kasan_save_stack+0x38/0x70 __kasan_kmalloc+0x8c/0xd0 __kmalloc+0x34c/0x5bc tnc_insert+0x140/0x16a4 ubifs_tnc_add+0x370/0x52c ubifs_jnl_write_data+0x5d8/0x870 do_writepage+0x36c/0x510 ubifs_writepage+0x190/0x4dc __writepage+0x58/0x154 write_cache_pages+0x394/0x830 do_writepages+0x1f0/0x5b0 filemap_fdatawrite_wbc+0x170/0x25c file_write_and_wait_range+0x140/0x190 ubifs_fsync+0xe8/0x290 vfs_fsync_range+0xc0/0x1e4 do_fsync+0x40/0x90 __arm64_sys_fsync+0x34/0x50 invoke_syscall.constprop.0+0xa8/0x260 do_el0_svc+0xc8/0x1f0 el0_svc+0x34/0x70 el0t_64_sync_handler+0x108/0x114 el0t_64_sync+0x1a4/0x1a8 Freed by task 403: kasan_save_stack+0x38/0x70 kasan_set_track+0x28/0x40 kasan_set_free_info+0x28/0x4c __kasan_slab_free+0xd4/0x13c kfree+0xc4/0x3a0 tnc_delete+0x3f4/0xe40 ubifs_tnc_remove_range+0x368/0x73c ubifs_tnc_remove_ino+0x29c/0x2e0 ubifs_jnl_delete_inode+0x150/0x260 ubifs_evict_inode+0x1d4/0x2e4 evict+0x1c8/0x450 iput+0x2a0/0x3c4 do_unlinkat+0x2cc/0x490 __arm64_sys_unlinkat+0x90/0x100 invoke_syscall.constprop.0+0xa8/0x260 do_el0_svc+0xc8/0x1f0 el0_svc+0x34/0x70 el0t_64_sync_handler+0x108/0x114 el0t_64_sync+0x1a4/0x1a8 The offending `memcpy()` in `ubifs_copy_hash()` has a use-after-free when a node becomes root in TNC but still has a `cparent` to an already freed node. More specifically, consider the following TNC: zroot / / zp1 / / zn Inserting a new node `zn_new` with a key smaller then `zn` will trigger a split in `tnc_insert()` if `zp1` is full: zroot / \ / \ zp1 zp2 / \ / \ zn_new zn `zn->parent` has now been moved to `zp2`, *but* `zn->cparent` still points to `zp1`. Now, consider a removal of all the nodes _except_ `zn`. Just when `tnc_delete()` is about to delete `zroot` and `zp2`: zroot \ \ zp2 \ \ zn `zroot` and `zp2` get freed and the tree collapses: zn `zn` now becomes the new `zroot`. `get_znodes_to_commit()` will now only find `zn`, the new `zroot`, and `write_index()` will check its `znode->cparent` that wrongly points to the already freed `zp1`. `ubifs_copy_hash()` thus gets wrongly called with `znode->cparent->zbranch[znode->iip].hash` that triggers the use-after-free! Fix this by explicitly setting `znode->cparent` to `NULL` in `get_znodes_to_commit()` for the root node. The search for the dirty nodes ---truncated---

A further deletion of other nodes in the\ntree (which also could free the nodes), the aforementioned node\u0027s\n`znode-\u003ecparent` could still point to a freed node. This\n`znode-\u003ecparent` may not be updated when getting nodes to commit in\n`ubifs_tnc_start_commit()`. This could then trigger a use-after-free\nwhen accessing the `znode-\u003ecparent` in `write_index()` in\n`ubifs_tnc_end_commit()`.\n\nThis can be triggered by running\n\n  rm -f /etc/test-file.bin\n  dd if=/dev/urandom of=/etc/test-file.bin bs=1M count=60 conv=fsync\n\nin a loop, and with `CONFIG_UBIFS_FS_AUTHENTICATION`.

More specifically, consider the following TNC:\n\n         zroot\n         /\n        /\n      zp1\n      /\n     /\n    zn\n\nInserting a new node `zn_new` with a key smaller then `zn` will trigger\na split in `tnc_insert()` if `zp1` is full:\n\n         zroot\n         /   \\\n        /     \\\n      zp1     zp2\n      /         \\\n     /           \\\n  zn_new          zn\n\n`zn-\u003eparent` has now been moved to `zp2`, *but* `zn-\u003ecparent` still\npoints to `zp1`.\n\nNow, consider a removal of all the nodes _except_ `zn`. Just when\n`tnc_delete()` is about to delete `zroot` and `zp2`:\n\n         zroot\n             \\\n              \\\n              zp2\n                \\\n                 \\\n                 zn\n\n`zroot` and `zp2` get freed and the tree collapses:\n\n           zn\n\n`zn` now becomes the new `zroot`.\n\n`get_znodes_to_commit()` will now only find `zn`, the new `zroot`, and\n`write_index()` will check its `znode-\u003ecparent` that wrongly points to\nthe already freed `zp1`. `ubifs_copy_hash()` thus gets wrongly called\nwith `znode-\u003ecparent-\u003ezbranch[znode-\u003eiip].hash` that triggers the\nuse-after-free!\n\nFix this by explicitly setting `znode-\u003ecparent` to `NULL` in\n`get_znodes_to_commit()` for the root node.

There is no network-facing or remote path into UBIFS TNC commit.\nAC:L - The attacker fully controls every step: they choose the file creation/deletion sequence that produces the split-then-collapse tree shape (upstream reproduces it with a two-line dd/rm loop), and unprivileged syncfs() forces the commit on demand rather than waiting on the ubifs_bgt background thread, so this is a deterministic dangling-pointer dereference rather than a race against an uncontrolled party.\nPR:L - Only an ordinary unprivileged local account is required \u2014 creating, writing, unlinking files in any writable directory on the mounted UBIFS volume plus a sync()/syncfs() call, all with no capability. Mounting is root-only, but in the realistic deployment (authenticated UBIFS as the embedded rootfs) the filesystem is already mounted at boot.\nUI:N - The attacker performs the entire sequence themselves with their own file operations and their own syncfs() call; no victim action, no separate mount, and no interaction with another user\u0027s files is needed.\nS:U - The freed znode and the corrupted slab both live in kernel heap memory managed by the same kernel security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The use-after-free corrupts a recycled generic-kmalloc object at an attacker-selectable offset, which can be leveraged to smash length, index, or pointer fields of sprayed structures (msg_msg, pipe buffers, keyring payloads) and turn them into an out-of-bounds kernel memory read, disclosing arbitrary kernel data.\nI:H - This is a 32-byte use-after-free WRITE (`memcpy(cparent-\u003ezbranch[ciip].hash, hash, 32)`, confirmed by KASAN\u0027s \"Write of size 32\") into a freed, spray-reallocatable slab object at one of several attacker-selectable offsets, giving a heap corruption primitive suitable for control-flow hijacking and local privilege escalation.\nA:H - The use-after-free write corrupts arbitrary recycled kernel heap objects and reliably produces oopses or panics, and it fires from the ubifs_bgt kthread or the commit path where failure marks the filesystem COMMIT_BROKEN/read-only, rendering the device unusable."
