The in-kernel API (`pkey_key2protkey`) and sysfs paths always pass a NULL apqn list with count 0.\nAC:L - `apqn_entries` is a plain u32 field copied directly from the ioctl argument struct, so the attacker sets the value outright in a single deterministic ioctl call. No race, no memory-layout dependency, and no condition outside the attacker\u0027s control.\nPR:L - The pkey miscdevice is registered with `.mode = 0666`, making it world read/write, and neither `pkey_unlocked_ioctl()` nor any of the four reachable sub-handlers performs a `capable()` or `CAP_*` check. Any local unprivileged user on an s390 system with CONFIG_PKEY enabled (standard in distro mainframe kernels) can trigger it.\nUI:N - The attacker issues the ioctl directly from their own process; no victim action, mount, or file open by another user is involved.\nS:U - The undersized allocation and the resulting out-of-bounds access are both in kernel heap memory within the same security authority. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - The size/count desynchronization causes the CCA handlers to walk `apqns[i]` far past the end of an attacker-sized kmalloc buffer, an unbounded slab out-of-bounds read rather than a few-byte overread. The disclosed heap contents are consumed as card/domain selectors, exposing adjacent kernel object data.\nI:L - All handler signatures take `const struct pkey_apqn *apqns`, so the desynchronized buffer is only ever read \u2014 there is no out-of-bounds write or control-flow hijack primitive. Integrity impact is limited to out-of-bounds heap values steering crypto-adapter requests to attacker-uncontrolled card/domain pairs.\nA:H - Iterating up to billions of entries past a small kmalloc\u0027d buffer reliably reaches unmapped memory, producing a kernel oops/panic, and the loop contains no `cond_resched()` so it can also stall the CPU. Any unprivileged local user can repeat this at will."

This may unexpectedly empty the child qdisc and thus\nmake an in-flight class passive via qlen_notify(). Most qdiscs do not\nexpect such behaviour at this point in time and may re-activate the\nclass eventually anyways which will lead to a use-after-free.\n\nThe referenced fix commit attempted to fix this behavior for the HFSC\ncase by moving the backlog accounting around, though this turned out to\nbe incomplete since the parent\u0027s parent may run into the issue too.\nThe following reproducer demonstrates this use-after-free:\n\n    tc qdisc add dev lo root handle 1: drr\n    tc filter add dev lo parent 1: basic classid 1:1\n    tc class add dev lo parent 1: classid 1:1 drr\n    tc qdisc add dev lo parent 1:1 handle 2: hfsc def 1\n    tc class add dev lo parent 2: classid 2:1 hfsc rt m1 8 d 1 m2 0\n    tc qdisc add dev lo parent 2:1 handle 3: netem\n    tc qdisc add dev lo parent 3:1 handle 4: blackhole\n\n    echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888\n    tc class delete dev lo classid 1:1\n    echo 1 | socat -u STDIN UDP4-DATAGRAM:127.0.0.1:8888\n\nSince backlog accounting issues leading to a use-after-frees on stale\nclass pointers is a recurring pattern at this point, this patch takes\na different approach. Instead of trying to fix the accounting, the patch\nensures that qdisc_tree_reduce_backlog always calls qlen_notify when\nthe child qdisc is empty. This solves the problem because deletion of\nqdiscs always involves a call to qdisc_reset() and / or\nqdisc_purge_queue() which ultimately resets its qlen to 0 thus causing\nthe following qdisc_tree_reduce_backlog() to report to the parent. Note\nthat this may call qlen_notify on passive classes multiple times. This\nis not a problem after the recent patch series that made all the\nclassful qdiscs qlen_notify() handlers idempotent."

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: Return NULL when htb_lookup_leaf encounters an empty rbtree\n\nhtb_lookup_leaf has a BUG_ON that can trigger with the following:\n\ntc qdisc del dev lo root\ntc qdisc add dev lo root handle 1: htb default 1\ntc class add dev lo parent 1: classid 1:1 htb rate 64bit\ntc qdisc add dev lo parent 1:1 handle 2: netem\ntc qdisc add dev lo parent 2:1 handle 3: blackhole\nping -I lo -c1 -W0.001 127.0.0.1\n\nThe root cause is the following:\n\n1. htb_dequeue calls htb_dequeue_tree which calls the dequeue handler on\n   the selected leaf qdisc\n2. netem_dequeue calls enqueue on the child qdisc\n3. blackhole_enqueue drops the packet and returns a value that is not\n   just NET_XMIT_SUCCESS\n4. Because of this, netem_dequeue calls qdisc_tree_reduce_backlog, and\n   since qlen is now 0, it calls htb_qlen_notify -\u003e htb_deactivate -\u003e\n   htb_deactiviate_prios -\u003e htb_remove_class_from_row -\u003e htb_safe_rb_erase\n5. As this is the only class in the selected hprio rbtree,\n   __rb_change_child in __rb_erase_augmented sets the rb_root pointer to\n   NULL\n6. Because blackhole_dequeue returns NULL, netem_dequeue returns NULL,\n   which causes htb_dequeue_tree to call htb_lookup_leaf with the same\n   hprio rbtree, and fail the BUG_ON\n\nThe function graph for this scenario is shown here:\n 0)               |  htb_enqueue() {\n 0) + 13.635 us   |    netem_enqueue();\n 0)   4.719 us    |    htb_activate_prios();\n 0) # 2249.199 us |  }\n 0)               |  htb_dequeue() {\n 0)   2.355 us    |    htb_lookup_leaf();\n 0)               |    netem_dequeue() {\n 0) + 11.061 us   |      blackhole_enqueue();\n 0)               |      qdisc_tree_reduce_backlog() {\n 0)               |        qdisc_lookup_rcu() {\n 0)   1.873 us    |          qdisc_match_from_root();\n 0)   6.292 us    |        }\n 0)   1.894 us    |        htb_search();\n 0)               |        htb_qlen_notify() {\n 0)   2.655 us    |          htb_deactivate_prios();\n 0)   6.933 us    |        }\n 0) + 25.227 us   |      }\n 0)   1.983 us    |      blackhole_dequeue();\n 0) + 86.553 us   |    }\n 0) # 2932.761 us |    qdisc_warn_nonwc();\n 0)               |    htb_lookup_leaf() {\n 0)               |      BUG_ON();\n ------------------------------------------\n\nThe full original bug report can be seen here [1].\n\nWe can fix this just by returning NULL instead of the BUG_ON,\nas htb_dequeue_tree returns NULL when htb_lookup_leaf returns\nNULL.\n\n[1] https://lore.kernel.org/netdev/pF5XOOIim0IuEfhI-SOxTgRvNoDwuux7UHKnE_Y5-zVd4wmGvNk2ceHjKb8ORnzw0cGwfmVu42g9dL7XyJLf1NEzaztboTWcm0Ogxuojoeo=@willsroot.io/"

No victim action is needed.\nS:U - The corruption is confined to kernel heap objects within the same kernel security authority; there is no VM, IOMMU, or sandbox boundary crossed.\nC:H - qfq_dump_class()/qfq_dump_class_stats() read class_weight and lmax from an already-freed qfq_aggregate and copy them to userspace via netlink, and the broader use-after-free on a generic kmalloc slab object can be groomed into an arbitrary kernel-memory read primitive.\nI:H - The unlocked qfq_rm_from_agg()/qfq_update_agg()/qfq_destroy_agg() in qfq_delete_class() write into a concurrently freed aggregate (list unlink plus several field stores) and can double-free it, giving heap-spray-based write primitives suitable for control-flow hijack and privilege escalation.\nA:H - The race trivially produces a NULL pointer dereference on cl-\u003eagg, a use-after-free oops, a double free, or a divide-by-zero from corrupted num_classes/wsum, any of which panics the kernel."

USB HID is an additional but strictly less severe (physical) path.\nAC:L - The attacker fully and deterministically controls both trigger conditions through the report descriptor \u2014 declaring an unnumbered (ID 0) report and picking a size so that hid_report_len(report)+7 lands exactly on a kmalloc slab-size boundary \u2014 with no race to win and no dependence on state the attacker cannot influence.\nPR:N - A HID peripheral needs no credentials or account on the target; the report descriptor is fetched and parsed, and feature/output reports are requested, automatically during device setup and driver probe (hid_hw_request(), mt_get_feature(), the hidinput LED worker, etc.).\nUI:N - Descriptor parsing and the subsequent report requests happen automatically during HID device enumeration and probe, with no action required from a logged-in user; an already-paired or reconnecting Bluetooth HID device reaches the code with no interaction at all.\nS:U - The under-allocation and the resulting heap corruption are both confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The buffer is one byte short of its documented contract in both directions, so on GET_REPORT paths adjacent slab bytes are mixed into data fed back through hid_report_raw_event() and into driver reads such as hid-steam\u0027s `memcpy(data, buf + 1, ...)`; per kernel scoring guidance, heap corruption of this kind is leverageable for information disclosure.\nI:H - This is an out-of-bounds heap write of attacker-influenced report data one byte past a kmalloc\u0027d object, and because the attacker picks the report size they can align the allocation to a slab boundary so the overflow lands in the adjacent object \u2014 a classic primitive for control-flow hijacking via heap grooming.\nA:H - Corrupting the neighbouring slab object (or its metadata) readily produces oopses, slab corruption panics, and KASAN-detected slab-out-of-bounds aborts, and the attacking peripheral can retrigger it at will by reconnecting."
