"value": "AV:A - The UAF is in pcan_usb_fd_decode_canmsg/decode_status on the USB bulk RX path that delivers CAN/CAN-FD frames from a PEAK USB FD adapter. In the highest realistic deployment (automotive/industrial host with the adapter already attached and the CAN netdev up), an attacker on the shared CAN bus can send frames that the adapter forwards into this decode path, which is an adjacent-segment attack analogous to Bluetooth/WiFi rather than a pure physical plug-in.\nAC:L - Any received CAN frame or status message that takes the decode path calls peak_usb_netif_rx() and then dereferences the can_frame alias; the attacker fully controls frame generation on the bus and does not depend on an uncontrollable race or rare memory layout to trigger the use-after-free.\nPR:N - CAN-bus peers need no host account or capability; once the PEAK interface is up in normal operation, URB completion runs in kernel context with no authentication of on-bus traffic.\nUI:N - No separate victim action is required beyond the already-deployed adapter and up interface; on-bus frames are processed automatically by peak_usb_read_bulk_callback \u2192 pcan_usb_fd_decode_buf.\nS:U - Impact is confined to the same host kernel that owns the peak_usb driver and skb allocator; this is ordinary kernel memory corruption, not a VM escape, IOMMU bypass, or other cross-authority boundary crossing.\nC:H - This is a use-after-free of an sk_buff/can_frame after ownership transfer to netif_rx; UAF of heap objects enables reclaim and disclosure of freed object contents, so confidentiality is scored High.\nI:H - The same UAF allows heap reuse of the freed skb object and is treated as providing a corruption/write primitive suitable for control-flow hijack under kernel UAF guidance, so integrity is High.\nA:H - Use-after-free of skb memory after netif_rx can oops/panic when the object is reused or unmapped, and UAF bugs are scored High availability even when not fully exploited for code execution."

The commit confirms it reproduces with a stock LTP test (pcrypt_aead01) once the loop is delayed, meaning it is a naturally occurring, repeatable window.\nPR:L - A basic unprivileged local user can both instantiate and continuously drive pcrypt via AF_ALG (`alg_bind` performs no capability check) and trigger the teardown side, since `crypto_alg_finish_registration()` \u2192 `crypto_remove_spawns()` destroys the pcrypt instance when an equal-or-higher-priority same-named implementation registers \u2014 a module autoload reachable from the same unprivileged bind path.\nUI:N - Exploitation is entirely attacker-driven through socket operations and crypto requests; no victim action, mount, or file open is required.\nS:U - The use-after-free corrupts kernel slab memory and stays within the kernel\u0027s own security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Reclaiming the freed `struct parallel_data` gives the attacker control of `pd-\u003ereorder_list`, whose per-CPU dereference in `padata_find_next()` becomes an attacker-directed kernel read, and `pd-\u003eps-\u003epinst` is likewise dereferenced \u2014 yielding disclosure of arbitrary kernel memory.\nI:H - The same UAF provides write primitives \u2014 `list_del_init()` unlink on an attacker-controlled reorder list, `++pd-\u003eprocessed` / `pd-\u003ecpu` writes, and most severely `queue_work(pinst-\u003eserial_wq, \u0026pd-\u003ereorder_work)` invoking a function pointer living in freed, sprayable memory, enabling control-flow hijack and privilege escalation.\nA:H - Even unweaponized, the slab-use-after-free reported by KASAN dereferences freed percpu and workqueue pointers from a kworker context, reliably producing an oops or kernel panic and taking the system down."

Triggering enqueue only needs sending a packet over the local device.\nUI:N - The attacker performs every step \u2014 qdisc/class setup, packet transmission, and class deletion \u2014 with no action from any other user or administrator.\nS:U - The corruption and its consequences are confined to the kernel\u0027s own memory and scheduling structures within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed hfsc_class remains linked in the parent\u0027s vt_tree/cf_tree and the eligible rbtree, so subsequent rbtree traversals read attacker-groomed heap contents; a UAF of a slab object with reclaimed contents yields a kernel information-disclosure primitive.\nI:H - Stale rb_node links cause rb_insert_color()/rb_erase()/vttree_update() to write into freed memory that the attacker can reclaim with a controlled object, giving a write primitive suitable for control-flow hijacking and privilege escalation. The doubly-inserted el_node additionally corrupts the eligible rbtree structure itself.\nA:H - Even without weaponization, the use-after-free and corrupted rbtree produce oopses, hangs on cyclic tree traversal, or a kernel panic, taking the whole system down."

If the child qdisc uses qdisc_peek_dequeued(), this may\ntrigger an immediate dequeue and potential packet drop. In such cases,\nqdisc_tree_reduce_backlog() is called, but the HFSC qdisc\u0027s qlen and backlog\nhave not yet been updated, leading to inconsistent queue accounting. This\ncan leave an empty HFSC class in the active list, causing further\nconsequences like use-after-free.\n\nThis patch fixes the bug by moving the increment of sch-\u003eq.qlen and\nsch-\u003eqstats.backlog before the call to the child qdisc\u0027s peek() operation.\nThis ensures that queue length and backlog are always accurate when packet\ndrops or dequeues are triggered during the peek."

Per kernel scoring guidance, tc/netlink qdisc configuration is a local attack vector.\nAC:L - The attacker fully controls both the qdisc hierarchy (hfsc + netem with an inner qdisc that rejects on enqueue) and the packet that drives hfsc_enqueue(), so the peek-time drop and the resulting qlen underflow are triggered deterministically with no race to win and no reliance on uncontrolled state.\nPR:L - Qdisc configuration is gated by netlink_net_capable(CAP_NET_ADMIN) against the netns owning user_ns, which any unprivileged user obtains via `unshare -Urn` and then applies to lo/dummy/veth inside the namespace. No real root in the init namespace is needed.\nUI:N - The attacker performs the qdisc setup and generates the triggering traffic entirely on their own; no victim action or interaction is required.\nS:U - The corruption is confined to kernel scheduler state in the same security authority; it is a standard local kernel privilege escalation with no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - The accounting inconsistency leaves a freed/empty hfsc_class linked in the eligible and vt-trees, and the commit explicitly states this leads to use-after-free; a UAF on a ~512-byte generic-kmalloc object with embedded rb_nodes yields a controlled read primitive over sprayed kernel objects.\nI:H - Dangling rb_node linkage of a freed hfsc_class means subsequent eltree/vttree insert, update, and rebalance operations write attacker-influenced values into reclaimed heap memory, giving a write primitive suitable for control-flow hijacking and privilege escalation.\nA:H - Even without full exploitation, the q.qlen/backlog underflow to 0xFFFFFFFF and the stale active-list entry cause use-after-free oopses, KASAN splats, and reported infinite loops in hfsc_dequeue(), crashing or hanging the machine."

Remote peers cannot set up or reach this configuration, so local access is required.\nAC:L - The attacker fully controls every precondition \u2014 the HFSC_RSC class flags, netem\u0027s duplicate probability (settable to 100%), and the TBF rate that stalls dequeue \u2014 so the reentrant double-insertion is triggered deterministically on demand, with no race or state outside attacker control.\nPR:L - CAP_NET_ADMIN is required for tc configuration, but rtnetlink checks it namespace-relative, so an unprivileged user obtains it by creating a user+network namespace (unshare -Urn) and building the qdisc hierarchy on a loopback/dummy device inside it.\nUI:N - The attacker performs the qdisc setup and generates the triggering traffic entirely on their own; no action by any other user or administrator is involved.\nS:U - The corruption is confined to kernel heap memory managed by the same kernel security authority; there is no crossing of a VM, IOMMU, or other trust boundary.\nC:H - The stale eligible-tree edge to a freed hfsc_class yields a use-after-free that is read from during rbtree traversal in eltree_get_mindl()/eltree_get_minel(), and reclaiming the freed slab object with attacker-controlled data gives an arbitrary kernel-memory read primitive.\nI:H - rb_insert_color() and rb_erase() write parent/color pointers into the freed object and into attacker-groomed neighbors, providing a controllable write primitive on reclaimed heap memory that is leverageable for full local privilege escalation.\nA:H - Even without full exploitation, the double insertion causes an infinite loop in hfsc_dequeue() or a use-after-free oops/panic, hanging or crashing the kernel."

"value": "AV:L - The race is driven entirely through local syscalls \u2014 a PUD-aligned MAP_SHARED hugetlbfs/MAP_HUGETLB mapping plus munmap/mremap/mprotect/fallocate to trigger huge_pmd_unshare(), raced against gup_fast() reached via O_DIRECT, io_uring registered buffers or vmsplice. There is no network-facing path into mm/hugetlb.c.\nAC:L - The attacker controls every participant: one thread issues the GUP-fast pin, a sibling thread issues the unmap that calls huge_pmd_unshare(), and a second attacker process reuses the now-exclusively-owned PMD table, and the whole sequence can be looped indefinitely. The gup_fast() IRQ-disabled window can additionally be widened by requesting a full PUD-sized pin range, since the PUD is latched once at the start of gup_fast_pud_range() while the PMD loop then walks 512 entries.\nPR:L - hugetlb_file_setup() performs no capable() check for MAP_HUGETLB anonymous mappings, and none of huge_pmd_unshare()\u0027s callers or the GUP-fast entry points require any capability, so an ordinary local user account suffices. Only a configured hugepage pool is needed, which is standard on cloud, virtualization, DPDK and database hosts.\nUI:N - Exploitation is fully self-contained \u2014 the attacker forks its own second process to establish PMD sharing and to repurpose the unshared page table. No victim action is required at any point.\nS:U - The defect and its impact are both within the kernel\u0027s own memory-management security authority, with no VM, IOMMU or sandbox boundary crossed. This is a standard kernel memory-safety/privilege-escalation shape, so scope remains Unchanged.\nC:H - A gup_fast() walker that latched the stale PUD proceeds to walk a PMD table that now backs a different process\u0027s address space, pinning and returning struct pages that belong to that other mm. Handing those pages to O_DIRECT or vmsplice yields a direct read primitive against another process\u0027s memory, which on hosts where a hugetlbfs segment is shared across trust boundaries (QEMU/vhost-user, DPDK/SPDK, shared DB segments) discloses privileged data.\nI:H - The same stale walk with FOLL_WRITE returns writable pins on pages mapped by the foreign address space, so an O_DIRECT read or io_uring write into that buffer modifies another process\u0027s memory arbitrarily. It also leaves DMA pins and page reference/mapcount state established behind the back of the owning mm, corrupting page-table and pinning invariants the kernel relies on.\nA:H - GUP-fast traversing page tables of an unrelated address space while that process is concurrently tearing down and re-populating them is exactly the unsynchronized page-table access the kernel elsewhere prevents with tlb_remove_table_sync_one(), and it readily produces inconsistent refcount/mapcount state, VM_WARN/BUG trips, and oops in mm paths. The race can be re-armed in a loop by an unprivileged process."

Remote packets alone cannot establish the required qdisc hierarchy.\nAC:L - The attacker fully controls every precondition \u2014 the qdisc/class topology, the child qdisc that re-enters `qdisc_tree_reduce_backlog()`, the packet, and the class deletion \u2014 and the sibling commit ships a deterministic shell reproducer. This is a reentrancy/accounting bug, not a race the attacker must win.\nPR:L - `tc` qdisc/class operations are gated by `netlink_net_capable(skb, CAP_NET_ADMIN)`, which resolves to `netlink_ns_capable(skb, sock_net(sk)-\u003euser_ns, ...)` \u2014 namespace-relative, so an unprivileged user obtains it with `unshare -Urn` and can build the full hierarchy on `lo` inside that netns.\nUI:N - The attacker performs the qdisc setup, packet transmission, and class deletion entirely on their own; no victim action or cooperation is needed.\nS:U - The corruption is confined to kernel memory within the same security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - Dangling `hfsc_class` rb_nodes left in `q-\u003eeligible`/`vt_tree` are dereferenced by `eltree_get_mindl()`/`vttree_get_minvt()` after `kfree()`, giving a use-after-free read over reclaimed heap contents the attacker can spray, enabling arbitrary kernel memory disclosure.\nI:H - Double `rb_erase()` on a stale node writes through an attacker-influenceable parent pointer, and subsequent `eltree_update()`/`rb_insert` operate on freed memory \u2014 yielding a write primitive; the same HFSC rbtree-corruption primitive has a public working local privilege escalation (CVE-2025-38001, \"rbtree family drama\").\nA:H - Red-black tree corruption and use-after-free on freed `hfsc_class` objects reliably produce oopses, KASAN splats, and kernel panics, taking the system down."
