Title

drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flip

Summary

In the Linux kernel, the following vulnerability has been resolved: drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flip It's possible that mtk_crtc->event is NULL in mtk_drm_crtc_finish_page_flip(). pending_needs_vblank value is set by mtk_crtc->event, but in mtk_drm_crtc_atomic_flush(), it's is not guarded by the same lock in mtk_drm_finish_page_flip(), thus a race condition happens. Consider the following case: CPU1 CPU2 step 1: mtk_drm_crtc_atomic_begin() mtk_crtc->event is not null, step 1: mtk_drm_crtc_atomic_flush: mtk_drm_crtc_update_config( !!mtk_crtc->event) step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip: lock mtk_crtc->event set to null, pending_needs_vblank set to false unlock pending_needs_vblank set to true, step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip called again, pending_needs_vblank is still true //null pointer Instead of guarding the entire mtk_drm_crtc_atomic_flush(), it's more efficient to just check if mtk_crtc->event is null before use.

[Fix] Place the disconnect_flag assignment operation after all code in pvr2_context_disconnect() to avoid this issue.

CVE-2024-26878 (GCVE-0-2024-26878)

Vulnerability from cvelistv5 – Published: 2024-04-17 10:27 – Updated: 2026-05-12 11:49

Title

quota: Fix potential NULL pointer dereference

Summary

In the Linux kernel, the following vulnerability has been resolved: quota: Fix potential NULL pointer dereference Below race may cause NULL pointer dereference P1 P2 dquot_free_inode quota_off drop_dquot_ref remove_dquot_ref dquots = i_dquot(inode) dquots = i_dquot(inode) srcu_read_lock dquots[cnt]) != NULL (1) dquots[type] = NULL (2) spin_lock(&dquots[cnt]->dq_dqb_lock) (3) .... If dquot_free_inode(or other routines) checks inode's quota pointers (1) before quota_off sets it to NULL(2) and use it (3) after that, NULL pointer dereference will be triggered. So let's fix it by using a temporary pointer to avoid this issue.

CVE-2024-26880 (GCVE-0-2024-26880)

Title

dm: call the resume method on internal suspend

Summary

In the Linux kernel, the following vulnerability has been resolved: dm: call the resume method on internal suspend There is this reported crash when experimenting with the lvm2 testsuite. The list corruption is caused by the fact that the postsuspend and resume methods were not paired correctly; there were two consecutive calls to the origin_postsuspend function. The second call attempts to remove the "hash_list" entry from a list, while it was already removed by the first call. Fix __dm_internal_resume so that it calls the preresume and resume methods of the table's targets. If a preresume method of some target fails, we are in a tricky situation. We can't return an error because dm_internal_resume isn't supposed to return errors. We can't return success, because then the "resume" and "postsuspend" methods would not be paired correctly. So, we set the DMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace tools, but it won't cause a kernel crash. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:56! invalid opcode: 0000 [#1] PREEMPT SMP CPU: 1 PID: 8343 Comm: dmsetup Not tainted 6.8.0-rc6 #4 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014 RIP: 0010:__list_del_entry_valid_or_report+0x77/0xc0 <snip> RSP: 0018:ffff8881b831bcc0 EFLAGS: 00010282 RAX: 000000000000004e RBX: ffff888143b6eb80 RCX: 0000000000000000 RDX: 0000000000000001 RSI: ffffffff819053d0 RDI: 00000000ffffffff RBP: ffff8881b83a3400 R08: 00000000fffeffff R09: 0000000000000058 R10: 0000000000000000 R11: ffffffff81a24080 R12: 0000000000000001 R13: ffff88814538e000 R14: ffff888143bc6dc0 R15: ffffffffa02e4bb0 FS: 00000000f7c0f780(0000) GS:ffff8893f0a40000(0000) knlGS:0000000000000000 CS: 0010 DS: 002b ES: 002b CR0: 0000000080050033 CR2: 0000000057fb5000 CR3: 0000000143474000 CR4: 00000000000006b0 Call Trace: <TASK> ? die+0x2d/0x80 ? do_trap+0xeb/0xf0 ? __list_del_entry_valid_or_report+0x77/0xc0 ? do_error_trap+0x60/0x80 ? __list_del_entry_valid_or_report+0x77/0xc0 ? exc_invalid_op+0x49/0x60 ? __list_del_entry_valid_or_report+0x77/0xc0 ? asm_exc_invalid_op+0x16/0x20 ? table_deps+0x1b0/0x1b0 [dm_mod] ? __list_del_entry_valid_or_report+0x77/0xc0 origin_postsuspend+0x1a/0x50 [dm_snapshot] dm_table_postsuspend_targets+0x34/0x50 [dm_mod] dm_suspend+0xd8/0xf0 [dm_mod] dev_suspend+0x1f2/0x2f0 [dm_mod] ? table_deps+0x1b0/0x1b0 [dm_mod] ctl_ioctl+0x300/0x5f0 [dm_mod] dm_compat_ctl_ioctl+0x7/0x10 [dm_mod] __x64_compat_sys_ioctl+0x104/0x170 do_syscall_64+0x184/0x1b0 entry_SYSCALL_64_after_hwframe+0x46/0x4e RIP: 0033:0xf7e6aead <snip> ---[ end trace 0000000000000000 ]---

The second call attempts to remove the\n\"hash_list\" entry from a list, while it was already removed by the first\ncall.\n\nFix __dm_internal_resume so that it calls the preresume and resume\nmethods of the table\u0027s targets.\n\nIf a preresume method of some target fails, we are in a tricky situation.\nWe can\u0027t return an error because dm_internal_resume isn\u0027t supposed to\nreturn errors. We can\u0027t return success, because then the \"resume\" and\n\"postsuspend\" methods would not be paired correctly. So, we set the\nDMF_SUSPENDED flag and we fake normal suspend - it may confuse userspace\ntools, but it won\u0027t cause a kernel crash.\n\n------------[ cut here ]------------\nkernel BUG at lib/list_debug.c:56!\ninvalid opcode: 0000 [#1] PREEMPT SMP\nCPU: 1 PID: 8343 Comm: dmsetup Not tainted 6.8.0-rc6 #4\nHardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-2 04/01/2014\nRIP: 0010:__list_del_entry_valid_or_report+0x77/0xc0\n\u003csnip\u003e\nRSP: 0018:ffff8881b831bcc0 EFLAGS: 00010282\nRAX: 000000000000004e RBX: ffff888143b6eb80 RCX: 0000000000000000\nRDX: 0000000000000001 RSI: ffffffff819053d0 RDI: 00000000ffffffff\nRBP: ffff8881b83a3400 R08: 00000000fffeffff R09: 0000000000000058\nR10: 0000000000000000 R11: ffffffff81a24080 R12: 0000000000000001\nR13: ffff88814538e000 R14: ffff888143bc6dc0 R15: ffffffffa02e4bb0\nFS:  00000000f7c0f780(0000) GS:ffff8893f0a40000(0000) knlGS:0000000000000000\nCS:  0010 DS: 002b ES: 002b CR0: 0000000080050033\nCR2: 0000000057fb5000 CR3: 0000000143474000 CR4: 00000000000006b0\nCall Trace:\n \u003cTASK\u003e\n ? die+0x2d/0x80\n ? do_trap+0xeb/0xf0\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? do_error_trap+0x60/0x80\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? exc_invalid_op+0x49/0x60\n ? __list_del_entry_valid_or_report+0x77/0xc0\n ? asm_exc_invalid_op+0x16/0x20\n ? table_deps+0x1b0/0x1b0 [dm_mod]\n ? __list_del_entry_valid_or_report+0x77/0xc0\n origin_postsuspend+0x1a/0x50 [dm_snapshot]\n dm_table_postsuspend_targets+0x34/0x50 [dm_mod]\n dm_suspend+0xd8/0xf0 [dm_mod]\n dev_suspend+0x1f2/0x2f0 [dm_mod]\n ? table_deps+0x1b0/0x1b0 [dm_mod]\n ctl_ioctl+0x300/0x5f0 [dm_mod]\n dm_compat_ctl_ioctl+0x7/0x10 [dm_mod]\n __x64_compat_sys_ioctl+0x104/0x170\n do_syscall_64+0x184/0x1b0\n entry_SYSCALL_64_after_hwframe+0x46/0x4e\nRIP: 0033:0xf7e6aead\n\u003csnip\u003e\n---[ end trace 0000000000000000 ]---"

No race must be won and no unpredictable memory layout is required; the double `list_del()` / unbalanced `down_write()` is deterministic.\nPR:L - The dm ioctl path is administrative, but in the deployments where this matters (container runtimes using the devicemapper/thin storage driver, CSI storage plugins, privileged containers granted CAP_SYS_ADMIN, and appliances where LVM operations are delegated), the actor triggering it is a low-privileged tenant relative to the host kernel, consistent with how other device-mapper flaws in this subsystem are rated.\nUI:N - The attacker performs every step itself \u2014 table load, pool suspend/resume, device suspend/remove \u2014 through its own ioctl calls. No action by any other user or administrator is needed.\nS:U - The corruption and the resulting crash/hang are confined to the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The unbalanced postsuspend/resume corrupts kernel state \u2014 a global linked list (`_dm_origins`) is operated on with stale/poisoned entries, and targets keep serving I/O with desynchronized mapping metadata (dm-cache migration state, dm-integrity journal/commit sequence, dm-snapshot origin registration), which is memory/state corruption that can be steered toward exposing kernel or foreign-volume data.\nI:H - This is a kernel list-corruption bug (double `list_del()` on `dm_origin-\u003ehash_list`), and the missing `.resume`/`.preresume` calls leave targets running with committed-but-not-reinitialized on-disk state \u2014 dm-integrity\u0027s journal is re-initialized and its autocommit timer deleted while writes continue, and dm-cache/dm-raid mapping state is left stale, permitting silent corruption of data stored on the mapped device.\nA:H - The reported failure is `kernel BUG at lib/list_debug.c:56` (invalid opcode oops) in `origin_postsuspend` reached from `dm_suspend`, taken while `_origins_lock` is write-held, so the box either panics or permanently wedges all further dm/snapshot operations. Equivalent unbalanced paths in dm-cache (`prevent_background_work` \u2192 unmatched `down_write`) and dm-raid1 (`dm_rh_stop_recovery`) produce unkillable hangs holding `md-\u003esuspend_lock`."

net: ip_tunnel: make sure to pull inner header in ip_tunnel_rcv()

Summary

In the Linux kernel, the following vulnerability has been resolved: net: ip_tunnel: make sure to pull inner header in ip_tunnel_rcv() Apply the same fix than ones found in : 8d975c15c0cd ("ip6_tunnel: make sure to pull inner header in __ip6_tnl_rcv()") 1ca1ba465e55 ("geneve: make sure to pull inner header in geneve_rx()") We have to save skb->network_header in a temporary variable in order to be able to recompute the network_header pointer after a pskb_inet_may_pull() call. pskb_inet_may_pull() makes sure the needed headers are in skb->head. syzbot reported: BUG: KMSAN: uninit-value in __INET_ECN_decapsulate include/net/inet_ecn.h:253 [inline] BUG: KMSAN: uninit-value in INET_ECN_decapsulate include/net/inet_ecn.h:275 [inline] BUG: KMSAN: uninit-value in IP_ECN_decapsulate include/net/inet_ecn.h:302 [inline] BUG: KMSAN: uninit-value in ip_tunnel_rcv+0xed9/0x2ed0 net/ipv4/ip_tunnel.c:409 __INET_ECN_decapsulate include/net/inet_ecn.h:253 [inline] INET_ECN_decapsulate include/net/inet_ecn.h:275 [inline] IP_ECN_decapsulate include/net/inet_ecn.h:302 [inline] ip_tunnel_rcv+0xed9/0x2ed0 net/ipv4/ip_tunnel.c:409 __ipgre_rcv+0x9bc/0xbc0 net/ipv4/ip_gre.c:389 ipgre_rcv net/ipv4/ip_gre.c:411 [inline] gre_rcv+0x423/0x19f0 net/ipv4/ip_gre.c:447 gre_rcv+0x2a4/0x390 net/ipv4/gre_demux.c:163 ip_protocol_deliver_rcu+0x264/0x1300 net/ipv4/ip_input.c:205 ip_local_deliver_finish+0x2b8/0x440 net/ipv4/ip_input.c:233 NF_HOOK include/linux/netfilter.h:314 [inline] ip_local_deliver+0x21f/0x490 net/ipv4/ip_input.c:254 dst_input include/net/dst.h:461 [inline] ip_rcv_finish net/ipv4/ip_input.c:449 [inline] NF_HOOK include/linux/netfilter.h:314 [inline] ip_rcv+0x46f/0x760 net/ipv4/ip_input.c:569 __netif_receive_skb_one_core net/core/dev.c:5534 [inline] __netif_receive_skb+0x1a6/0x5a0 net/core/dev.c:5648 netif_receive_skb_internal net/core/dev.c:5734 [inline] netif_receive_skb+0x58/0x660 net/core/dev.c:5793 tun_rx_batched+0x3ee/0x980 drivers/net/tun.c:1556 tun_get_user+0x53b9/0x66e0 drivers/net/tun.c:2009 tun_chr_write_iter+0x3af/0x5d0 drivers/net/tun.c:2055 call_write_iter include/linux/fs.h:2087 [inline] new_sync_write fs/read_write.c:497 [inline] vfs_write+0xb6b/0x1520 fs/read_write.c:590 ksys_write+0x20f/0x4c0 fs/read_write.c:643 __do_sys_write fs/read_write.c:655 [inline] __se_sys_write fs/read_write.c:652 [inline] __x64_sys_write+0x93/0xd0 fs/read_write.c:652 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xcf/0x1e0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x63/0x6b Uninit was created at: __alloc_pages+0x9a6/0xe00 mm/page_alloc.c:4590 alloc_pages_mpol+0x62b/0x9d0 mm/mempolicy.c:2133 alloc_pages+0x1be/0x1e0 mm/mempolicy.c:2204 skb_page_frag_refill+0x2bf/0x7c0 net/core/sock.c:2909 tun_build_skb drivers/net/tun.c:1686 [inline] tun_get_user+0xe0a/0x66e0 drivers/net/tun.c:1826 tun_chr_write_iter+0x3af/0x5d0 drivers/net/tun.c:2055 call_write_iter include/linux/fs.h:2087 [inline] new_sync_write fs/read_write.c:497 [inline] vfs_write+0xb6b/0x1520 fs/read_write.c:590 ksys_write+0x20f/0x4c0 fs/read_write.c:643 __do_sys_write fs/read_write.c:655 [inline] __se_sys_write fs/read_write.c:652 [inline] __x64_sys_write+0x93/0xd0 fs/read_write.c:652 do_syscall_x64 arch/x86/entry/common.c:52 [inline] do_syscall_64+0xcf/0x1e0 arch/x86/entry/common.c:83 entry_SYSCALL_64_after_hwframe+0x63/0x6b

CVE-2024-26883 (GCVE-0-2024-26883)

Vulnerability from cvelistv5 – Published: 2024-04-17 10:27 – Updated: 2026-08-05 11:28

Title

bpf: Fix stackmap overflow check on 32-bit arches

Summary

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix stackmap overflow check on 32-bit arches The stackmap code relies on roundup_pow_of_two() to compute the number of hash buckets, and contains an overflow check by checking if the resulting value is 0. However, on 32-bit arches, the roundup code itself can overflow by doing a 32-bit left-shift of an unsigned long value, which is undefined behaviour, so it is not guaranteed to truncate neatly. This was triggered by syzbot on the DEVMAP_HASH type, which contains the same check, copied from the hashtab code. The commit in the fixes tag actually attempted to fix this, but the fix did not account for the UB, so the fix only works on CPUs where an overflow does result in a neat truncation to zero, which is not guaranteed. Checking the value before rounding does not have this problem.

CVE-2024-26884 (GCVE-0-2024-26884)

Vulnerability from cvelistv5 – Published: 2024-04-17 10:27 – Updated: 2026-08-05 11:28

Title

bpf: Fix hashtab overflow check on 32-bit arches

Summary

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix hashtab overflow check on 32-bit arches The hashtab code relies on roundup_pow_of_two() to compute the number of hash buckets, and contains an overflow check by checking if the resulting value is 0. However, on 32-bit arches, the roundup code itself can overflow by doing a 32-bit left-shift of an unsigned long value, which is undefined behaviour, so it is not guaranteed to truncate neatly. This was triggered by syzbot on the DEVMAP_HASH type, which contains the same check, copied from the hashtab code. So apply the same fix to hashtab, by moving the overflow check to before the roundup.

However, on 32-bit arches, the roundup code itself\ncan overflow by doing a 32-bit left-shift of an unsigned long value,\nwhich is undefined behaviour, so it is not guaranteed to truncate\nneatly. This was triggered by syzbot on the DEVMAP_HASH type, which\ncontains the same check, copied from the hashtab code. So apply the same\nfix to hashtab, by moving the overflow check to before the roundup."

A plain local user account therefore suffices.\nUI:N - The attacker performs the entire sequence themselves via two syscalls; no victim action, mount, or file open is needed.\nS:U - The corruption and its effects are confined to kernel memory within the same security authority; no hypervisor, IOMMU or sandbox boundary is crossed.\nC:H - A bogus n_buckets that escapes the overflow check leaves htab-\u003ebuckets as a zero-sized ZERO_SIZE_PTR allocation while __select_bucket() indexes it with an unmasked, key-derived 32-bit offset, so lookups read and dereference attacker-chosen out-of-bounds kernel memory, yielding an arbitrary-read primitive.\nI:H - The same wild bucket pointer is written through by htab_lock_bucket() (raw_spinlock acquire) and hlist_nulls_add_head_rcu() during map update, giving an out-of-bounds write of kernel list pointers at an attacker-influenced offset \u2014 a corruption primitive suitable for control-flow hijack.\nA:H - The identical pattern was demonstrated by syzbot as a kernel crash on arm32, and even the benign UB outcome (n_buckets == 1 with a ~4-billion entry limit) forces unbounded hash-chain walks under a raw spinlock with IRQs disabled, producing hard lockups, RCU stalls and panics."

CVE-2024-26889 (GCVE-0-2024-26889)

Vulnerability from cvelistv5 – Published: 2024-04-17 10:27 – Updated: 2026-05-23 15:39

Title

Bluetooth: hci_core: Fix possible buffer overflow

Summary

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix possible buffer overflow struct hci_dev_info has a fixed size name[8] field so in the event that hdev->name is bigger than that strcpy would attempt to write past its size, so this fixes this problem by switching to use strscpy.

Severity

5.5 (Medium)

Title

Bluetooth: btrtl: fix out of bounds memory access

Summary

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btrtl: fix out of bounds memory access The problem is detected by KASAN. btrtl driver uses private hci data to store 'struct btrealtek_data'. If btrtl driver is used with btusb, then memory for private hci data is allocated in btusb. But no private data is allocated after hci_dev, when btrtl is used with hci_h5. This commit adds memory allocation for hci_h5 case. ================================================================== BUG: KASAN: slab-out-of-bounds in btrtl_initialize+0x6cc/0x958 [btrtl] Write of size 8 at addr ffff00000f5a5748 by task kworker/u9:0/76 Hardware name: Pine64 PinePhone (1.2) (DT) Workqueue: hci0 hci_power_on [bluetooth] Call trace: dump_backtrace+0x9c/0x128 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 print_report+0xf8/0x5d8 kasan_report+0x90/0xd0 __asan_store8+0x9c/0xc0 [btrtl] h5_btrtl_setup+0xd0/0x2f8 [hci_uart] h5_setup+0x50/0x80 [hci_uart] hci_uart_setup+0xd4/0x260 [hci_uart] hci_dev_open_sync+0x1cc/0xf68 [bluetooth] hci_dev_do_open+0x34/0x90 [bluetooth] hci_power_on+0xc4/0x3c8 [bluetooth] process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Allocated by task 53: kasan_save_stack+0x3c/0x68 kasan_save_track+0x20/0x40 kasan_save_alloc_info+0x68/0x78 __kasan_kmalloc+0xd4/0xd8 __kmalloc+0x1b4/0x3b0 hci_alloc_dev_priv+0x28/0xa58 [bluetooth] hci_uart_register_device+0x118/0x4f8 [hci_uart] h5_serdev_probe+0xf4/0x178 [hci_uart] serdev_drv_probe+0x54/0xa0 really_probe+0x254/0x588 __driver_probe_device+0xc4/0x210 driver_probe_device+0x64/0x160 __driver_attach_async_helper+0x88/0x158 async_run_entry_fn+0xd0/0x388 process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Last potentially related work creation: kasan_save_stack+0x3c/0x68 __kasan_record_aux_stack+0xb0/0x150 kasan_record_aux_stack_noalloc+0x14/0x20 __queue_work+0x33c/0x960 queue_work_on+0x98/0xc0 hci_recv_frame+0xc8/0x1e8 [bluetooth] h5_complete_rx_pkt+0x2c8/0x800 [hci_uart] h5_rx_payload+0x98/0xb8 [hci_uart] h5_recv+0x158/0x3d8 [hci_uart] hci_uart_receive_buf+0xa0/0xe8 [hci_uart] ttyport_receive_buf+0xac/0x178 flush_to_ldisc+0x130/0x2c8 process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Second to last potentially related work creation: kasan_save_stack+0x3c/0x68 __kasan_record_aux_stack+0xb0/0x150 kasan_record_aux_stack_noalloc+0x14/0x20 __queue_work+0x788/0x960 queue_work_on+0x98/0xc0 __hci_cmd_sync_sk+0x23c/0x7a0 [bluetooth] __hci_cmd_sync+0x24/0x38 [bluetooth] btrtl_initialize+0x760/0x958 [btrtl] h5_btrtl_setup+0xd0/0x2f8 [hci_uart] h5_setup+0x50/0x80 [hci_uart] hci_uart_setup+0xd4/0x260 [hci_uart] hci_dev_open_sync+0x1cc/0xf68 [bluetooth] hci_dev_do_open+0x34/0x90 [bluetooth] hci_power_on+0xc4/0x3c8 [bluetooth] process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 ==================================================================

No network or adjacent-network data reaches the vulnerable code, and the UART-attached controller is a permanently soldered on-board device rather than a hot-plugged one.\nAC:L - The overflow is unconditional and fully deterministic \u2014 `sizeof_priv` is zero for every RTL H5 device, so every single `btrtl_initialize()`/`btrtl_download_firmware()` run writes past the end of the `hci_dev` allocation with no race, no timing window, and no memory grooming required. It reproduces on the first attempt on every affected system, as the reported KASAN splat from a stock PinePhone boot shows.\nPR:L - An unprivileged local session user on the affected phone/tablet/laptop class can re-trigger the write at will, because `h5_btrtl_resume()` performs a `device_reprobe()` on RTL8723BS parts and a suspend/resume cycle is permitted to active local sessions by default logind/polkit policy, re-running the full setup path. The write also fires with zero privileges during the automatic boot-time probe; the root/`CAP_NET_ADMIN`-gated `HCIDEVUP` ioctl is only one of several trigger routes, not a required one.\nUI:N - The out-of-bounds write executes in a kernel workqueue during automatic device probe and power-on, with no administrator or victim action of any kind. The suspend/resume re-trigger is initiated by the attacker\u0027s own process.\nS:U - The corruption is confined to the kernel slab of the same host and is exploited by, and against, the kernel\u0027s own security authority. No hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - `btrtl_dmp_hdr()` reads the out-of-bounds `rtl_dump.controller` and `rtl_dump.driver_name` fields back as pointers and `snprintf(\"%s\", ...)`s them into a devcoredump buffer that userspace can read from `/sys/class/devcoredump/`; when that region overlaps a neighbouring slab object whose contents have since changed, this becomes a read of an attacker-influenceable kernel pointer and disclosure of arbitrary kernel memory. The out-of-bounds region also exposes adjacent heap contents to the driver\u0027s own logic (`btrealtek_test_flag`, firmware-version reporting).\nI:H - This is a confirmed slab out-of-bounds write (KASAN \"Write of size 8\") of up to 32 bytes \u2014 two kernel `.rodata` pointers, a firmware-derived `u32`, and a `set_bit()` \u2014 immediately past the `hci_dev` allocation, at a fixed and predictable offset. Depending on kernel version, architecture, and config (`sizeof(struct hci_dev)` relative to the kmalloc bucket, particularly on the 32-bit ARM boards that use this exact driver), those bytes land in the head of the adjacent heap object, giving a repeatable heap-overflow primitive that can be groomed by controlling what occupies the neighbouring slot.\nA:H - Corrupting the first bytes of a neighbouring kmalloc object, and later dereferencing pointers read back out of bounds in `btrtl_dmp_hdr()`, readily produces a kernel oops or panic; the access is repeated on every probe, resume, and device open. On builds with KASAN or arm64 MTE (shipped in production on some Android devices), the very first occurrence is a fatal report/panic, and `panic_on_warn`/`panic_on_oops` hardened embedded and automotive builds turn it into an immediate full system outage."
