Per kernel scoring guidance, tc/netlink qdisc configuration is Local.\nAC:L - With `netem duplicate 100%` the reentrant enqueue and the resulting double `list_add_tail()` occur deterministically on the very first packet \u2014 no race, no timing window, and no dependence on memory layout the attacker cannot influence. The attacker fully controls the qdisc tree, the classifier, and the traffic.\nPR:L - Qdisc creation needs CAP_NET_ADMIN, but rtnetlink checks it via `netlink_net_capable()` against the netns\u0027s user_ns, so an unprivileged user obtains it with `unshare -Urn` and configures ETS+netem on a dummy/veth/lo device inside their own namespace. No real root is needed.\nUI:N - The attacker triggers the corruption entirely on their own by sending a packet through the qdisc they configured. No victim action is required.\nS:U - The corruption is confined to kernel memory within the same security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The double list add corrupts the `q-\u003eactive` doubly-linked list, desynchronizing the active/qlen invariant and leaving classes referencing `cl-\u003eqdisc` pointers that are freed by `qdisc_put()` before being NULLed \u2014 a use-after-free read of heap contents the attacker can groom, allowing kernel pointer and adjacent-object disclosure.\nI:H - `__list_add()` on an already-linked node performs attacker-influenced `prev-\u003enext`/`next-\u003eprev` stores, and the resulting stale-active class yields writes through a dangling `cl-\u003eqdisc` during dequeue/teardown; this is a classic list-corruption write primitive leveraged for heap grooming and control-flow hijack.\nA:H - The corrupted list causes a `CONFIG_DEBUG_LIST` `__list_add_valid()` BUG/oops, and otherwise leaves the qdisc permanently wedged \u2014 `ets_qdisc_dequeue()` returns NULL with `sch-\u003eq.qlen \u003e 0`, stalling the device\u0027s transmit path \u2014 plus NULL/dangling `cl-\u003eqdisc-\u003eops-\u003epeek()` dereferences leading to a kernel panic."

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."

[0]\n\nFrom the splat, a thread close()d a vhci file descriptor while\nits device was being used by iotcl() on another thread.\n\nOnce the last fd refcnt is released, vhci_release() calls\nhci_unregister_dev(), hci_free_dev(), and kfree() for struct\nvhci_data, which is set to hci_dev-\u003edev-\u003edriver_data.\n\nThe problem is that there is no synchronisation after unlinking\nhdev from hci_dev_list in hci_unregister_dev().  There might be\nanother thread still accessing the hdev which was fetched before\nthe unlink operation.\n\nWe can use SRCU for such synchronisation.\n\nLet\u0027s run hci_dev_reset() under SRCU and wait for its completion\nin hci_unregister_dev().\n\nAnother option would be to restore hci_dev-\u003edestruct(), which was\nremoved in commit 587ae086f6e4 (\"Bluetooth: Remove unused\nhci-destruct cb\").  However, this would not be a good solution, as\nwe should not run hci_unregister_dev() while there are in-flight\nioctl() requests, which could lead to another data-race KCSAN splat.\n\nNote that other drivers seem to have the same problem, for exmaple,\nvirtbt_remove().\n\n[0]:\nBUG: KASAN: slab-use-after-free in skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline]\nBUG: KASAN: slab-use-after-free in skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937\nRead of size 8 at addr ffff88807cb8d858 by task syz.1.219/6718\n\nCPU: 1 UID: 0 PID: 6718 Comm: syz.1.219 Not tainted 6.16.0-rc1-syzkaller-00196-g08207f42d3ff #0 PREEMPT(full)\nHardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 05/07/2025\nCall Trace:\n \u003cTASK\u003e\n dump_stack_lvl+0x189/0x250 lib/dump_stack.c:120\n print_address_description mm/kasan/report.c:408 [inline]\n print_report+0xd2/0x2b0 mm/kasan/report.c:521\n kasan_report+0x118/0x150 mm/kasan/report.c:634\n skb_queue_empty_lockless include/linux/skbuff.h:1891 [inline]\n skb_queue_purge_reason+0x99/0x360 net/core/skbuff.c:3937\n skb_queue_purge include/linux/skbuff.h:3368 [inline]\n vhci_flush+0x44/0x50 drivers/bluetooth/hci_vhci.c:69\n hci_dev_do_reset net/bluetooth/hci_core.c:552 [inline]\n hci_dev_reset+0x420/0x5c0 net/bluetooth/hci_core.c:592\n sock_do_ioctl+0xd9/0x300 net/socket.c:1190\n sock_ioctl+0x576/0x790 net/socket.c:1311\n vfs_ioctl fs/ioctl.c:51 [inline]\n __do_sys_ioctl fs/ioctl.c:907 [inline]\n __se_sys_ioctl+0xf9/0x170 fs/ioctl.c:893\n do_syscall_x64 arch/x86/entry/syscall_64.c:63 [inline]\n do_syscall_64+0xfa/0x3b0 arch/x86/entry/syscall_64.c:94\n entry_SYSCALL_64_after_hwframe+0x77/0x7f\nRIP: 0033:0x7fcf5b98e929\nCode: ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 0f 1f 40 00 48 89 f8 48 89 f7 48 89 d6 48 89 ca 4d 89 c2 4d 89 c8 4c 8b 4c 24 08 0f 05 \u003c48\u003e 3d 01 f0 ff ff 73 01 c3 48 c7 c1 a8 ff ff ff f7 d8 64 89 01 48\nRSP: 002b:00007fcf5c7b9038 EFLAGS: 00000246 ORIG_RAX: 0000000000000010\nRAX: ffffffffffffffda RBX: 00007fcf5bbb6160 RCX: 00007fcf5b98e929\nRDX: 0000000000000000 RSI: 00000000400448cb RDI: 0000000000000009\nRBP: 00007fcf5ba10b39 R08: 0000000000000000 R09: 0000000000000000\nR10: 0000000000000000 R11: 0000000000000246 R12: 0000000000000000\nR13: 0000000000000000 R14: 00007fcf5bbb6160 R15: 00007ffd6353d528\n \u003c/TASK\u003e\n\nAllocated by task 6535:\n kasan_save_stack mm/kasan/common.c:47 [inline]\n kasan_save_track+0x3e/0x80 mm/kasan/common.c:68\n poison_kmalloc_redzone mm/kasan/common.c:377 [inline]\n __kasan_kmalloc+0x93/0xb0 mm/kasan/common.c:394\n kasan_kmalloc include/linux/kasan.h:260 [inline]\n __kmalloc_cache_noprof+0x230/0x3d0 mm/slub.c:4359\n kmalloc_noprof include/linux/slab.h:905 [inline]\n kzalloc_noprof include/linux/slab.h:1039 [inline]\n vhci_open+0x57/0x360 drivers/bluetooth/hci_vhci.c:635\n misc_open+0x2bc/0x330 drivers/char/misc.c:161\n chrdev_open+0x4c9/0x5e0 fs/char_dev.c:414\n do_dentry_open+0xdf0/0x1970 fs/open.c:964\n vfs_open+0x3b/0x340 fs/open.c:1094\n do_open fs/namei.c:3887 [inline]\n path_openat+0x2ee5/0x3830 fs/name\n---truncated---"

Both sides of the race are local syscalls.\nAC:L - The attacker controls both racing threads (close of the vhci fd vs. the HCIDEVRESET ioctl) and the window is large, spanning the full `hci_dev_close_sync()`/`hci_dev_open_sync()` command-sync sequence inside `hci_dev_do_reset()`. Failed attempts are harmless and can be repeated indefinitely until the race is won.\nPR:L - `HCIDEVRESET` is gated on `capable(CAP_NET_ADMIN)`, a capability held by non-root service accounts such as bluetoothd and Android\u0027s Bluetooth process rather than requiring full init-namespace root, and this repo consistently scores CAP_NET_ADMIN-gated Bluetooth mgmt/ioctl bugs as PR:L. The free side additionally needs no privilege at all when supplied by ordinary transport-driver teardown (btusb/hci_ldisc/virtio_bt unregister).\nUI:N - The attacker drives both the reset ioctl and the device teardown from its own threads with no victim participation. No user action of any kind is needed.\nS:U - The use-after-free corrupts kernel heap memory and yields kernel-privilege compromise within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a slab use-after-free on a `kmalloc-1k` object; `skb_queue_purge_reason()` reads the freed `sk_buff_head` and dereferences pointers taken from it, so an attacker who reclaims the slot obtains an arbitrary kernel-memory read primitive and full disclosure of kernel memory.\nI:H - The UAF is read *and* write: `skb_queue_splice_init()` writes back into the freed object and `kfree_skb()` is invoked on attacker-reclaimable pointers, while `vhci_send_frame()` performs `skb_queue_tail()` into freed memory. That combination gives a controlled-free and linked-list-write primitive suitable for control-flow hijacking and privilege escalation.\nA:H - Even without successful heap grooming, purging a freed skb queue and freeing garbage pointers reliably corrupts the slab allocator and panics the kernel. The attacker can trigger it repeatedly for a persistent denial of service."

There is no network-facing path into posix-cpu-timers.\nAC:L - The attacker controls both sides of the race: it arms the CPU timer expiry, chooses the precise moment of `release_task()` by calling `waitpid()` from its own parent/tracer, and issues the concurrent `timer_delete()` from a sibling thread \u2014 retryable in a tight loop and widenable by queueing up to 20 timers on the firing list. Real-world exploitation of this exact bug confirms it is reliably winnable.\nPR:L - No capability or permission check exists anywhere on the path \u2014 `validate_clock_permissions()`/`pid_for_clock()` gate only on thread-group/pid existence, and `grep` for `capable`/`CAP_` in both posix-timers files returns nothing. Any unprivileged local user, including a seccomp-confined Android app UID, can reach it.\nUI:N - The attacker\u0027s own processes and threads perform every step \u2014 creating the timer, exiting the traced thread, reaping it, and deleting the timer. No victim action of any kind is needed.\nS:U - The use-after-free corrupts kernel heap objects and escalates within the kernel\u0027s own security authority, which is standard kernel privilege escalation. No hypervisor, IOMMU, or other security-authority boundary is crossed.\nC:H - The freed `struct sigqueue` is linked into the signal pending list by `send_sigqueue()` and later copied out to userspace through `dequeue_signal()`/`rt_sigtimedwait()`, disclosing whatever now occupies the reclaimed slab object \u2014 an effectively arbitrary kernel-memory read. The `do_cpu_nanosleep()` variant additionally exposes reclaimed kernel stack.\nI:H - `send_sigqueue()` writes into the freed object (`q-\u003einfo.si_overrun++`) and performs a `list_add_tail()` linked-list insertion on attacker-resprayable memory, followed by a double free on dequeue \u2014 a classic controlled-write primitive leading to full privilege escalation, as demonstrated by in-the-wild exploitation of this flaw.\nA:H - Even without successful exploitation the race causes `BUG_ON(!(q-\u003eflags \u0026 SIGQUEUE_PREALLOC))` in `send_sigqueue()`, `WARN_ON_ONCE()` in the delete path, list corruption, and a double free \u2014 any of which oops or panic the kernel.

Exploitation is via local syscalls (`socket(AF_TIPC)`, `connect`, `write`, `unshare`/exit).\nAC:L - The attacker controls both sides of the race \u2014 they choose when to destroy the netns and simultaneously keep `tipc_conn_recv_work()` running by streaming malformed subscription writes that force `tipc_conn_close()`/`conn_put()`. The sequence can be retried in an unbounded create/destroy-netns loop, and syzkaller reproduced it by chance alone.\nPR:L - Only an unprivileged local account is needed: `unshare -Urn` creates the netns that instantiates and later tears down the per-netns topology server, `socket(AF_TIPC,\u2026)` autoloads tipc.ko with no capability check in `__sock_create()`, and `net/tipc/` has no `capable()` gate on the socket or subscription path.\nUI:N - The attacker performs every step themselves \u2014 namespace creation, connecting to the topology server, sending data, and triggering namespace teardown. No victim action or cooperation is required.\nS:U - The use-after-free corrupts kernel heap memory and any resulting escalation stays within the kernel\u0027s own security authority. No hypervisor, IOMMU, or other security-authority boundary is crossed.\nC:H - The freed object lives in the generic kmalloc-512 cache, which an unprivileged attacker can reliably reclaim with `msg_msg`/`setxattr`/keyring sprays, giving control over `con-\u003esock` and `con-\u003esub_list`; the resulting controlled dereferences and list walks can be turned into a kernel-memory read primitive and leak kernel pointers.\nI:H - Post-free, `tipc_conn_close()` writes through the reclaimed object (`test_and_clear_bit` on `con-\u003eflags`, `write_lock_bh` on an attacker-controlled `sk`), unlinks attacker-controlled `con-\u003esub_list` entries (arbitrary-write via list_del), and calls `sock-\u003eops-\u003eshutdown()` through a controlled pointer \u2014 a direct control-flow hijack primitive leading to privilege escalation.\nA:H - Even unweaponized, the use-after-free dereferences freed memory in the `cleanup_net` kworker, producing an oops/panic in a global kernel thread as demonstrated by the syzbot KASAN report. A panic in the netns cleanup worker also wedges all further namespace teardown on the system."
