No local access to the target is required.\nAC:L - The double `list_add` of the same `work-\u003einterim_entry` in `smb2_open()` is deterministic, not racy, and the attacker owns both connections so it chooses exactly when the peer\u0027s `oplock_info` is released relative to `ksmbd_free_work_struct()`, and can loop the sequence indefinitely. Per guidance, an attacker-created ordering and a use-after-free are Low.\nPR:L - Reaching `smb_grant_oplock()`/`smb_break_all_oplock()` requires a completed SESSION_SETUP, TREE_CONNECT and SMB2 CREATE, so an authenticated but otherwise unprivileged share account (including a mapped guest) is needed. This matches the scoring of the sibling post-authentication ksmbd oplock UAFs.\nUI:N - The attacker drives every step from its own two SMB sessions \u2014 take the oplock, issue the conflicting overwrite CREATE, then close or drop the first connection. No administrator or other client has to do anything.\nS:U - The list corruption and its consequences stay entirely within the kernel\u0027s own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The stale `interim_list` head lets `smb2_lease_break_noti()` treat reclaimed heap memory as a `struct ksmbd_work`, dereferencing its `conn`, `sess`, and `request_buf` fields, and `smb2_send_interim_resp()` then transmits data derived from that object back to the attacker \u2014 an arbitrary kernel memory disclosure primitive after a heap spray.\nI:H - `list_del()` in `ksmbd_free_work_struct()` writes two attacker-influenced kernel heap pointers at a fixed offset into a freed kmalloc-256 slot that the attacker can reclaim with a chosen object, and the fake-`ksmbd_work` path yields further controlled pointer writes and indirect calls, giving control-flow hijack.\nA:H - Even unweaponized, the `list_del` on freed memory trips `CONFIG_DEBUG_LIST`/`BUG()` or silently corrupts the slab, and walking the dangling `interim_list` oopses the ksmbd worker; the attacker can repeat it at will to keep the file server down."

Title
Bluetooth: L2CAP: Fix slab-use-after-free Read in l2cap_send_cmd
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Fix slab-use-after-free Read in l2cap_send_cmd
After the hci sync command releases l2cap_conn, the hci receive data work
queue references the released l2cap_conn when sending to the upper layer.
Add hci dev lock to the hci receive data work queue to synchronize the two.

A remote peer can trigger it repeatedly to panic the system."

Title
net/mlx5: Bridge, fix the crash caused by LAG state check
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Bridge, fix the crash caused by LAG state check
When removing LAG device from bridge, NETDEV_CHANGEUPPER event is
triggered. Driver finds the lower devices (PFs) to flush all the
offloaded entries. And mlx5_lag_is_shared_fdb is checked, it returns
false if one of PF is unloaded. In such case,
mlx5_esw_bridge_lag_rep_get() and its caller return NULL, instead of
the alive PF, and the flush is skipped.
Besides, the bridge fdb entry's lastuse is updated in mlx5 bridge
event handler. But this SWITCHDEV_FDB_ADD_TO_BRIDGE event can be
ignored in this case because the upper interface for bond is deleted,
and the entry will never be aged because lastuse is never updated.
To make things worse, as the entry is alive, mlx5 bridge workqueue
keeps sending that event, which is then handled by kernel bridge
notifier. It causes the following crash when accessing the passed bond
netdev which is already destroyed.
To fix this issue, remove such checks. LAG state is already checked in
commit 15f8f168952f ("net/mlx5: Bridge, verify LAG state when adding
bond to bridge"), driver still need to skip offload if LAG becomes
invalid state after initialization.

But this SWITCHDEV_FDB_ADD_TO_BRIDGE event can be\nignored in this case because the upper interface for bond is deleted,\nand the entry will never be aged because lastuse is never updated.\n\nTo make things worse, as the entry is alive, mlx5 bridge workqueue\nkeeps sending that event, which is then handled by kernel bridge\nnotifier. It causes the following crash when accessing the passed bond\nnetdev which is already destroyed.\n\nTo fix this issue, remove such checks. LAG state is already checked in\ncommit 15f8f168952f (\"net/mlx5: Bridge, verify LAG state when adding\nbond to bridge\"), driver still need to skip offload if LAG becomes\ninvalid state after initialization.\n\n Oops: stack segment: 0000 [#1] SMP\n CPU: 3 UID: 0 PID: 23695 Comm: kworker/u40:3 Tainted: G OE 6.11.0_mlnx #1\n Tainted: [O]=OOT_MODULE, [E]=UNSIGNED_MODULE\n Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014\n Workqueue: mlx5_bridge_wq mlx5_esw_bridge_update_work [mlx5_core]\n RIP: 0010:br_switchdev_event+0x2c/0x110 [bridge]\n Code: 44 00 00 48 8b 02 48 f7 00 00 02 00 00 74 69 41 54 55 53 48 83 ec 08 48 8b a8 08 01 00 00 48 85 ed 74 4a 48 83 fe 02 48 89 d3 \u003c4c\u003e 8b 65 00 74 23 76 49 48 83 fe 05 74 7e 48 83 fe 06 75 2f 0f b7\n RSP: 0018:ffffc900092cfda0 EFLAGS: 00010297\n RAX: ffff888123bfe000 RBX: ffffc900092cfe08 RCX: 00000000ffffffff\n RDX: ffffc900092cfe08 RSI: 0000000000000001 RDI: ffffffffa0c585f0\n RBP: 6669746f6e690a30 R08: 0000000000000000 R09: ffff888123ae92c8\n R10: 0000000000000000 R11: fefefefefefefeff R12: ffff888123ae9c60\n R13: 0000000000000001 R14: ffffc900092cfe08 R15: 0000000000000000\n FS: 0000000000000000(0000) GS:ffff88852c980000(0000) knlGS:0000000000000000\n CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n CR2: 00007f15914c8734 CR3: 0000000002830005 CR4: 0000000000770ef0\n DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000\n DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400\n PKRU: 55555554\n Call Trace:\n \u003cTASK\u003e\n ? __die_body+0x1a/0x60\n ? die+0x38/0x60\n ? do_trap+0x10b/0x120\n ? do_error_trap+0x64/0xa0\n ? exc_stack_segment+0x33/0x50\n ? asm_exc_stack_segment+0x22/0x30\n ? br_switchdev_event+0x2c/0x110 [bridge]\n ? sched_balance_newidle.isra.149+0x248/0x390\n notifier_call_chain+0x4b/0xa0\n atomic_notifier_call_chain+0x16/0x20\n mlx5_esw_bridge_update+0xec/0x170 [mlx5_core]\n mlx5_esw_bridge_update_work+0x19/0x40 [mlx5_core]\n process_scheduled_works+0x81/0x390\n worker_thread+0x106/0x250\n ? bh_worker+0x110/0x110\n kthread+0xb7/0xe0\n ? kthread_park+0x80/0x80\n ret_from_fork+0x2d/0x50\n ? kthread_park+0x80/0x80\n ret_from_fork_asm+0x11/0x20\n \u003c/TASK\u003e"

Title
net: mctp: unshare packets when reassembling
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: mctp: unshare packets when reassembling
Ensure that the frag_list used for reassembly isn't shared with other
packets. This avoids incorrect reassembly when packets are cloned, and
prevents a memory leak due to circular references between fragments and
their skb_shared_info.
The upcoming MCTP-over-USB driver uses skb_clone which can trigger the
problem - other MCTP drivers don't share SKBs.
A kunit test is added to reproduce the issue.
Severity
8.8 (High)

net/mlx5: handle errors in mlx5_chains_create_table()
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: handle errors in mlx5_chains_create_table()
In mlx5_chains_create_table(), the return value of mlx5_get_fdb_sub_ns()
and mlx5_get_flow_namespace() must be checked to prevent NULL pointer
dereferences. If either function fails, the function should log error
message with mlx5_core_warn() and return error pointer.
Severity
No CVSS data available.
