No capability, and no CIFS mount ownership, is required.\nUI:N - No victim action is needed: the attacker\u0027s own access to a multiuser mount creates and tears down per-fsuid SMB sessions, and ordinary background CIFS mount/reconnect/prune activity supplies the teardown otherwise.\nS:U - The use-after-free occurs in kernel memory and its effects stay within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - Contents of the freed `cifs_tcon` \u2014 including `tree_name` printed with `%s`, which reads until a NUL and can run past the freed object \u2014 are copied into the seq_file buffer returned to the unprivileged reader, yielding a kernel heap disclosure that can be aimed at reallocated sensitive data via heap grooming.\nI:H - A use-after-free of this class gives the attacker influence over the freed slab object\u0027s contents, letting dereferenced pointers (`server-\u003eops-\u003eprint_stats`, tcon list links) be steered by heap spraying into a control-flow/corruption primitive rather than a mere stale read.\nA:H - The confirmed sibling bug produced a general protection fault on slab poison in exactly this traversal, and the oops happens while the global `cifs_tcp_ses_lock` spinlock is held, hanging all subsequent CIFS operations system-wide on top of killing the faulting task."

No network protocol handler parses attacker data into this function.\nAC:L - The attacker simply reads a sysfs file; the code path is deterministic, repeatable, and involves no race, no memory-layout grooming, and no condition that must happen to occur at exploit time. Whether a qualifying DT node exists is a static property of the target platform, which CVSS treats as target configuration rather than attack complexity.\nPR:L - Any unprivileged local account can read `/sys/devices/.../uevent` and `/sys/devices/.../modalias`, which are mode 0644 and 0444 respectively \u2014 no capability, no user namespace, and no root is required.\nUI:N - The attacker triggers the code path entirely on their own by reading a sysfs attribute; no victim needs to mount a filesystem, plug in a device, or take any other action.\nS:U - The defect and its consequences are confined to the kernel\u0027s own address space and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The write cursor is advanced past the end of the caller\u0027s buffer while the length accounting goes negative, and the loop guard omits the NUL terminator \u2014 out-of-bounds accounting adjacent to a heap-allocated `kobj_uevent_env` that is subsequently copied straight back to userspace, which can expose adjacent kernel heap contents.\nI:H - The commit adds an explicit buffer overflow check because `str` is left pointing beyond the buffer\u0027s end with a corrupted remaining-length value; out-of-bounds write accounting on a kernel heap buffer is scored High per out-of-bounds-write guidance.\nA:H - Corrupting memory past the end of a `kmalloc`\u0027d uevent buffer can smash adjacent slab objects or redzones, producing a kernel oops or panic, and the path can be re-triggered arbitrarily often by an unprivileged reader."

There is no network-facing consumer of btrfs_lookup_extent_info().\nAC:L - The triggering condition is a static, fully attacker-controlled on-disk value (extent item refs == 0) that the tree checker does not reject, so the crafted image deterministically hits the BUG_ON on the first COW or snapshot-delete of the affected block. No race, timing window, or memory-layout dependency is involved.\nPR:L - Once a crafted or inconsistent btrfs is mounted \u2014 routinely via desktop/kiosk automount (udisks2/systemd), shared storage, or container images \u2014 any unprivileged local user with write access drives btrfs_force_cow_block()/btrfs_drop_snapshot() into the assertion; no capability check gates the path.\nUI:N - After the filesystem is present, the attacker triggers the fault entirely through their own file writes or a subvolume delete, with no action required from any other user. Automount removes the need for a victim to explicitly mount the device.\nS:U - The crash and any resulting metadata corruption are confined to the kernel and the affected btrfs filesystem, within the same security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The assertion is btrfs\u0027s last line of defense before operating on an extent with broken reference bookkeeping; when it is bypassed (CONFIG_BUG=n embedded/IoT builds) update_ref_for_cow() takes the last-reference path and frees a still-referenced tree block, producing cross-linked extents that expose one file\u0027s or subvolume\u0027s data through another. The oops itself also dumps kernel registers, stack contents, and pointers to the log.\nI:H - Continuing past a zero refcount causes btrfs to free and re-allocate live metadata blocks, giving the attacker arbitrary corruption of extent-tree and file data belonging to other users on the filesystem. The oops additionally aborts a transaction mid-flight, leaving on-disk state inconsistent.\nA:H - BUG_ON() panics the kernel outright under panic_on_oops; otherwise the task is killed while still holding delayed_refs-\u003elock, head-\u003emutex, and tree locks, so every subsequent delayed-ref operation on that filesystem spins or blocks forever \u2014 an unrecoverable filesystem-wide hang and potential hard lockup, which is exactly why the fix unlocks all three before returning -EUCLEAN."

The pmd_trans_huge() check is racy and can lead to a BUG_ON() (if you hit\n   the right two race windows) - I\u0027ve tested this in a kernel build with\n   some extra mdelay() calls. See the commit message for a description\n   of the race scenario.\n   On older kernels (before 6.5), I think the same bug can even\n   theoretically lead to accessing transhuge page contents as a page table\n   if you hit the right 5 narrow race windows (I haven\u0027t tested this case).\n2. As pointed out by Qi Zheng, pmd_trans_huge() is not sufficient for\n   detecting PMDs that don\u0027t point to page tables.\n   On older kernels (before 6.5), you\u0027d just have to win a single fairly\n   wide race to hit this.\n   I\u0027ve tested this on 6.1 stable by racing migration (with a mdelay()\n   patched into try_to_migrate()) against UFFDIO_ZEROPAGE - on my x86\n   VM, that causes a kernel oops in ptlock_ptr().\n3. On newer kernels (\u003e=6.5), for shmem mappings, khugepaged is allowed\n   to yank page tables out from under us (though I haven\u0027t tested that),\n   so I think the BUG_ON() checks in mfill_atomic() are just wrong.\n\nI decided to write two separate fixes for these (one fix for bugs 1+2, one\nfix for bug 3), so that the first fix can be backported to kernels\naffected by bugs 1+2.\n\n\nThis patch (of 2):\n\nThis fixes two issues.\n\nI discovered that the following race can occur:\n\n  mfill_atomic                other thread\n  ============                ============\n                              \u003czap PMD\u003e\n  pmdp_get_lockless() [reads none pmd]\n  \u003cbail if trans_huge\u003e\n  \u003cif none:\u003e\n                              \u003cpagefault creates transhuge zeropage\u003e\n    __pte_alloc [no-op]\n                              \u003czap PMD\u003e\n  \u003cbail if pmd_trans_huge(*dst_pmd)\u003e\n  BUG_ON(pmd_none(*dst_pmd))\n\nI have experimentally verified this in a kernel with extra mdelay() calls;\nthe BUG_ON(pmd_none(*dst_pmd)) triggers.\n\nOn kernels newer than commit 0d940a9b270b (\"mm/pgtable: allow\npte_offset_map[_lock]() to fail\"), this can\u0027t lead to anything worse than\na BUG_ON(), since the page table access helpers are actually designed to\ndeal with page tables concurrently disappearing; but on older kernels\n(\u003c=6.4), I think we could probably theoretically race past the two\nBUG_ON() checks and end up treating a hugepage as a page table.\n\nThe second issue is that, as Qi Zheng pointed out, there are other types\nof huge PMDs that pmd_trans_huge() can\u0027t catch: devmap PMDs and swap PMDs\n(in particular, migration PMDs).\n\nOn \u003c=6.4, this is worse than the first issue: If mfill_atomic() runs on a\nPMD that contains a migration entry (which just requires winning a single,\nfairly wide race), it will pass the PMD to pte_offset_map_lock(), which\nassumes that the PMD points to a page table.\n\nBreakage follows: First, the kernel tries to take the PTE lock (which will\ncrash or maybe worse if there is no \"struct page\" for the address bits in\nthe migration entry PMD - I think at least on X86 there usually is no\ncorresponding \"struct page\" thanks to the PTE inversion mitigation, amd64\nlooks different).\n\nIf that didn\u0027t crash, the kernel would next try to write a PTE into what\nit wrongly thinks is a page table.\n\nAs part of fixing these issues, get rid of the check for pmd_trans_huge()\nbefore __pte_alloc() - that\u0027s redundant, we\u0027re going to have to check for\nthat after the __pte_alloc() anyway.\n\nBackport note: pmdp_get_lockless() is pmd_read_atomic() in older kernels."

This requires local execution on the target system; there is no remote or adjacent network path into `mm/userfaultfd.c`.\nAC:L - The attacker controls both sides of the race entirely from their own threads \u2014 one thread spins on `UFFDIO_ZEROPAGE`/`UFFDIO_COPY` while another drives `MADV_DONTNEED`/THP faults or forces PMD migration via `move_pages()`, NUMA balancing, or compaction \u2014 and the operation can be retried in a tight loop with no lockout or rate limit. The commit author characterizes the migration variant as \"a single, fairly wide race,\" and THP is enabled in essentially all production kernel configurations.\nPR:L - `userfaultfd_syscall_allowed()` returns true unconditionally when `UFFD_USER_MODE_ONLY` is set, so any unprivileged local user obtains a userfaultfd regardless of `CAP_SYS_PTRACE` or the `vm.unprivileged_userfaultfd` sysctl; on kernels in the affected range below 5.11 the syscall was unrestricted or defaulted to permitted. `validate_dst_vma()` only requires the target VMA to be uffd-registered, which the attacker does to their own mapping.\nUI:N - The attacker\u0027s own threads perform every step \u2014 creating the uffd, registering the VMA, and racing the ioctl against PMD teardown/migration. No victim action or interaction is involved.\nS:U - The corruption occurs in kernel page-table handling for the attacker\u0027s own mm and stays within the kernel\u0027s security authority, which is the standard local privilege-escalation scope. No hypervisor, IOMMU, or other trust boundary is crossed.\nC:H - On kernels \u22646.4 the kernel passes a migration/huge PMD to `pte_offset_map_lock()` and then writes a PTE into memory that is actually transhuge page contents the attacker has mapped, disclosing kernel-generated physical addresses and PTE flags. The resulting page-table-injection primitive can be leveraged into arbitrary physical memory reads.\nI:H - `set_pte_at()` writes a PTE into non-page-table memory at an attacker-influenced location, and `spin_lock()` is taken on a wild `ptlock_ptr()` derived from attacker-influenced PFN bits \u2014 both are kernel write primitives. Injecting attacker-controlled data into a structure used as a page table is a well-known route to arbitrary write and full control-flow hijack.\nA:H - The race reliably reaches `BUG_ON(pmd_none(*dst_pmd))`, which the author experimentally verified, and the migration-PMD variant produced a confirmed kernel oops in `ptlock_ptr()` on 6.1 stable. Either outcome is a kernel panic/oops, and it can be triggered repeatedly by any local user."
