Title
inet: inet_defrag: prevent sk release while still in use
Summary
In the Linux kernel, the following vulnerability has been resolved:
inet: inet_defrag: prevent sk release while still in use
ip_local_out() and other functions can pass skb->sk as function argument.
If the skb is a fragment and reassembly happens before such function call
returns, the sk must not be released.
This affects skb fragments reassembled via netfilter or similar
modules, e.g. openvswitch or ct_act.c, when run as part of tx pipeline.
Eric Dumazet made an initial analysis of this bug. Quoting Eric:
Calling ip_defrag() in output path is also implying skb_orphan(),
which is buggy because output path relies on sk not disappearing.
A relevant old patch about the issue was :
8282f27449bf ("inet: frag: Always orphan skbs inside ip_defrag()")
[..]
net/ipv4/ip_output.c depends on skb->sk being set, and probably to an
inet socket, not an arbitrary one.
If we orphan the packet in ipvlan, then downstream things like FQ
packet scheduler will not work properly.
We need to change ip_defrag() to only use skb_orphan() when really
needed, ie whenever frag_list is going to be used.
Eric suggested to stash sk in fragment queue and made an initial patch.
However there is a problem with this:
If skb is refragmented again right after, ip_do_fragment() will copy
head->sk to the new fragments, and sets up destructor to sock_wfree.
IOW, we have no choice but to fix up sk_wmem accouting to reflect the
fully reassembled skb, else wmem will underflow.
This change moves the orphan down into the core, to last possible moment.
As ip_defrag_offset is aliased with sk_buff->sk member, we must move the
offset into the FRAG_CB, else skb->sk gets clobbered.
This allows to delay the orphaning long enough to learn if the skb has
to be queued or if the skb is completing the reasm queue.
In the former case, things work as before, skb is orphaned. This is
safe because skb gets queued/stolen and won't continue past reasm engine.
In the latter case, we will steal the skb->sk reference, reattach it to
the head skb, and fix up wmem accouting when inet_frag inflates truesize.

Quoting Eric:\n Calling ip_defrag() in output path is also implying skb_orphan(),\n which is buggy because output path relies on sk not disappearing.\n\n A relevant old patch about the issue was :\n 8282f27449bf (\"inet: frag: Always orphan skbs inside ip_defrag()\")\n\n [..]\n\n net/ipv4/ip_output.c depends on skb-\u003esk being set, and probably to an\n inet socket, not an arbitrary one.\n\n If we orphan the packet in ipvlan, then downstream things like FQ\n packet scheduler will not work properly.\n\n We need to change ip_defrag() to only use skb_orphan() when really\n needed, ie whenever frag_list is going to be used.\n\nEric suggested to stash sk in fragment queue and made an initial patch.\nHowever there is a problem with this:\n\nIf skb is refragmented again right after, ip_do_fragment() will copy\nhead-\u003esk to the new fragments, and sets up destructor to sock_wfree.\nIOW, we have no choice but to fix up sk_wmem accouting to reflect the\nfully reassembled skb, else wmem will underflow.\n\nThis change moves the orphan down into the core, to last possible moment.\nAs ip_defrag_offset is aliased with sk_buff-\u003esk member, we must move the\noffset into the FRAG_CB, else skb-\u003esk gets clobbered.\n\nThis allows to delay the orphaning long enough to learn if the skb has\nto be queued or if the skb is completing the reasm queue.\n\nIn the former case, things work as before, skb is orphaned. This is\nsafe because skb gets queued/stolen and won\u0027t continue past reasm engine.\n\nIn the latter case, we will steal the skb-\u003esk reference, reattach it to\nthe head skb, and fix up wmem accouting when inet_frag inflates truesize."

No real root in the init namespace is required.\nUI:N - The attacker triggers the entire sequence from their own process with no action by any other user or administrator.\nS:U - The use-after-free corrupts kernel memory within the same security authority; there is no VM, IOMMU, or hypervisor boundary crossed.\nC:H - This is a use-after-free on `struct sock`; the confirmed KASAN splat is a slab-use-after-free *read* in `sk_fullsock()`/`ip_skb_dst_mtu()`, and reallocating the freed slab object under attacker-controlled data yields a general kernel-memory disclosure primitive.\nI:H - The stale `sk` is written to as well \u2014 `nf_queue_entry_get_refs()` does `sock_hold(state-\u003esk)` (refcount increment into freed memory) from the POST_ROUTING hook, and the freed `struct sock` is full of function pointers (`sk_destruct`, `sk_write_space`, `sk_backlog_rcv`, `sk_prot`) that become control-flow hijack primitives after heap grooming.\nA:H - The bug reliably produces a KASAN-reported slab-use-after-free and, without KASAN, dereferences of freed/reused socket memory and refcount corruption lead to kernel oops or panic."

Title
ksmbd: validate request buffer size in smb2_allocate_rsp_buf()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate request buffer size in smb2_allocate_rsp_buf()
The response buffer should be allocated in smb2_allocate_rsp_buf
before validating request. But the fields in payload as well as smb2 header
is used in smb2_allocate_rsp_buf(). This patch add simple buffer size
validation to avoid potencial out-of-bounds in request buffer.

Title
ksmbd: fix slab-out-of-bounds in smb2_allocate_rsp_buf
Summary
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix slab-out-of-bounds in smb2_allocate_rsp_buf
If ->ProtocolId is SMB2_TRANSFORM_PROTO_NUM, smb2 request size
validation could be skipped. if request size is smaller than
sizeof(struct smb2_query_info_req), slab-out-of-bounds read can happen in
smb2_allocate_rsp_buf(). This patch allocate response buffer after
decrypting transform request. smb3_decrypt_req() will validate transform
request size and avoid slab-out-of-bound in smb2_allocate_rsp_buf().

netfilter: nf_tables: Fix potential data-race in __nft_obj_type_get()
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_tables: Fix potential data-race in __nft_obj_type_get()
nft_unregister_obj() can concurrent with __nft_obj_type_get(),
and there is not any protection when iterate over nf_tables_objects
list in __nft_obj_type_get(). Therefore, there is potential data-race
of nf_tables_objects list entry.
Use list_for_each_entry_rcu() to iterate over nf_tables_objects
list in __nft_obj_type_get(), and use rcu_read_lock() in the caller
nft_obj_type_get() to protect the entire type query process.

Nothing about winning the window depends on state the attacker cannot influence or repeatedly re-attempt.\nPR:L - The only gate is `netlink_net_capable(skb, CAP_NET_ADMIN)`, which is evaluated against the network namespace\u0027s owning user namespace, so an ordinary unprivileged user obtains it with `unshare -Urn`. No real root or CAP_SYS_ADMIN in the initial namespace is required to reach the unsynchronized list walk.\nUI:N - The attacker triggers the entire sequence from their own process by sending netlink messages; no victim action, mount, file open, or administrator interaction is needed.\nS:U - The race and its consequences are confined to the kernel\u0027s own security authority \u2014 this is standard in-kernel memory corruption with no crossing of a VM, IOMMU, or hypervisor boundary.\nC:H - The unprotected traversal can dereference `struct nft_object_type` fields in module memory already released by `free_mod_mem()`, and the stale pointer is propagated into `nft_obj_init()` where `type-\u003emaxattr` and `type-\u003epolicy` steer a `kmalloc_array()` and `nla_parse_nested()`, giving an attacker-influenceable read out of reallocated kernel memory.\nI:H - `try_module_get(type-\u003eowner)` performs an atomic increment through a dangling pointer, and `nft_obj_init()` then invokes `type-\u003eselect_ops()` and `ops-\u003einit()` \u2014 indirect calls through function pointers read from freed vmalloc\u0027d module memory that can be reoccupied by a later module load or spray, yielding a control-flow hijack primitive.\nA:H - Following a stale list entry or a garbage `type-\u003eowner`/`select_ops` pointer produces an oops or panic, and the use-after-free reliably crashes the kernel even when not weaponized further."

Title
Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: Fix use-after-free bugs caused by sco_sock_timeout
When the sco connection is established and then, the sco socket
is releasing, timeout_work will be scheduled to judge whether
the sco disconnection is timeout. The sock will be deallocated
later, but it is dereferenced again in sco_sock_timeout. As a
result, the use-after-free bugs will happen. The root cause is
shown below:
Cleanup Thread | Worker Thread
sco_sock_release |
sco_sock_close |
__sco_sock_close |
sco_sock_set_timer |
schedule_delayed_work |
sco_sock_kill | (wait a time)
sock_put(sk) //FREE | sco_sock_timeout
| sock_hold(sk) //USE
The KASAN report triggered by POC is shown below:

Title
Bluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout
There is a race condition between l2cap_chan_timeout() and
l2cap_chan_del(). When we use l2cap_chan_del() to delete the
channel, the chan->conn will be set to null. But the conn could
be dereferenced again in the mutex_lock() of l2cap_chan_timeout().
As a result the null pointer dereference bug will happen. The
KASAN report triggered by POC is shown below:

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: l2cap: fix null-ptr-deref in l2cap_chan_timeout\n\nThere is a race condition between l2cap_chan_timeout() and\nl2cap_chan_del(). When we use l2cap_chan_del() to delete the\nchannel, the chan-\u003econn will be set to null. But the conn could\nbe dereferenced again in the mutex_lock() of l2cap_chan_timeout().\nAs a result the null pointer dereference bug will happen. The\nKASAN report triggered by POC is shown below:\n\n[ 472.074580] ==================================================================\n[ 472.075284] BUG: KASAN: null-ptr-deref in mutex_lock+0x68/0xc0\n[ 472.075308] Write of size 8 at addr 0000000000000158 by task kworker/0:0/7\n[ 472.075308]\n[ 472.075308] CPU: 0 PID: 7 Comm: kworker/0:0 Not tainted 6.9.0-rc5-00356-g78c0094a146b #36\n[ 472.075308] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.14.0-0-g155821a1990b-prebuilt.qemu4\n[ 472.075308] Workqueue: events l2cap_chan_timeout\n[ 472.075308] Call Trace:\n[ 472.075308] \u003cTASK\u003e\n[ 472.075308] dump_stack_lvl+0x137/0x1a0\n[ 472.075308] print_report+0x101/0x250\n[ 472.075308] ? __virt_addr_valid+0x77/0x160\n[ 472.075308] ? mutex_lock+0x68/0xc0\n[ 472.075308] kasan_report+0x139/0x170\n[ 472.075308] ? mutex_lock+0x68/0xc0\n[ 472.075308] kasan_check_range+0x2c3/0x2e0\n[ 472.075308] mutex_lock+0x68/0xc0\n[ 472.075308] l2cap_chan_timeout+0x181/0x300\n[ 472.075308] process_one_work+0x5d2/0xe00\n[ 472.075308] worker_thread+0xe1d/0x1660\n[ 472.075308] ? pr_cont_work+0x5e0/0x5e0\n[ 472.075308] kthread+0x2b7/0x350\n[ 472.075308] ? pr_cont_work+0x5e0/0x5e0\n[ 472.075308] ? kthread_blkcg+0xd0/0xd0\n[ 472.075308] ret_from_fork+0x4d/0x80\n[ 472.075308] ? kthread_blkcg+0xd0/0xd0\n[ 472.075308] ret_from_fork_asm+0x11/0x20\n[ 472.075308] \u003c/TASK\u003e\n[ 472.075308] ==================================================================\n[ 472.094860] Disabling lock debugging due to kernel taint\n[ 472.096136] BUG: kernel NULL pointer dereference, address: 0000000000000158\n[ 472.096136] #PF: supervisor write access in kernel mode\n[ 472.096136] #PF: error_code(0x0002) - not-present page\n[ 472.096136] PGD 0 P4D 0\n[ 472.096136] Oops: 0002 [#1] PREEMPT SMP KASAN NOPTI\n[ 472.096136] CPU: 0 PID: 7 Comm: kworker/0:0 Tainted: G B 6.9.0-rc5-00356-g78c0094a146b #36\n[ 472.096136] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.14.0-0-g155821a1990b-prebuilt.qemu4\n[ 472.096136] Workqueue: events l2cap_chan_timeout\n[ 472.096136] RIP: 0010:mutex_lock+0x88/0xc0\n[ 472.096136] Code: be 08 00 00 00 e8 f8 23 1f fd 4c 89 f7 be 08 00 00 00 e8 eb 23 1f fd 42 80 3c 23 00 74 08 48 88\n[ 472.096136] RSP: 0018:ffff88800744fc78 EFLAGS: 00000246\n[ 472.096136] RAX: 0000000000000000 RBX: 1ffff11000e89f8f RCX: ffffffff8457c865\n[ 472.096136] RDX: 0000000000000001 RSI: 0000000000000008 RDI: ffff88800744fc78\n[ 472.096136] RBP: 0000000000000158 R08: ffff88800744fc7f R09: 1ffff11000e89f8f\n[ 472.096136] R10: dffffc0000000000 R11: ffffed1000e89f90 R12: dffffc0000000000\n[ 472.096136] R13: 0000000000000158 R14: ffff88800744fc78 R15: ffff888007405a00\n[ 472.096136] FS: 0000000000000000(0000) GS:ffff88806d200000(0000) knlGS:0000000000000000\n[ 472.096136] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 472.096136] CR2: 0000000000000158 CR3: 000000000da32000 CR4: 00000000000006f0\n[ 472.096136] Call Trace:\n[ 472.096136] \u003cTASK\u003e\n[ 472.096136] ? __die_body+0x8d/0xe0\n[ 472.096136] ? page_fault_oops+0x6b8/0x9a0\n[ 472.096136] ? kernelmode_fixup_or_oops+0x20c/0x2a0\n[ 472.096136] ? do_user_addr_fault+0x1027/0x1340\n[ 472.096136] ? _printk+0x7a/0xa0\n[ 472.096136] ? mutex_lock+0x68/0xc0\n[ 472.096136] ? add_taint+0x42/0xd0\n[ 472.096136] ? exc_page_fault+0x6a/0x1b0\n[ 472.096136] ? asm_exc_page_fault+0x26/0x30\n[ 472.096136] ? mutex_lock+0x75/0xc0\n[ 472.096136] ? mutex_lock+0x88/0xc0\n[ 472.096136] ? mutex_lock+0x75/0xc0\n[ 472.096136] l2cap_chan_timeo\n---truncated---"

Title
firewire: nosy: ensure user_length is taken into account when fetching packet contents
Summary
In the Linux kernel, the following vulnerability has been resolved:
firewire: nosy: ensure user_length is taken into account when fetching packet contents
Ensure that packet_buffer_get respects the user_length provided. If
the length of the head packet exceeds the user_length, packet_buffer_get
will now return 0 to signify to the user that no data were read
and a larger buffer size is required. Helps prevent user space overflows.

"value": "AV:L - The vulnerability is triggered by a local `read(2)` syscall on the `/dev/nosy` character device, where the caller supplies the undersized `user_length` that the kernel then ignores. Although the overflowing bytes originate from the IEEE 1394 bus, the vulnerable code path itself is entered and controlled entirely through a local file-descriptor operation.\nAC:L - The attacker simply calls `read()` with a small `count` while any traffic is present on the snooped 1394 bus (cycle-start packets alone arrive every 125 \u00b5s, and a bus reset queues a packet), making the overflow reliably and repeatedly reproducible with no memory-layout or timing conditions outside the attacker\u0027s control.\nPR:L - `nosy.c` contains no capability or permission checks whatsoever \u2014 reachability is decided solely by the permissions on `/dev/nosy`, which on the developer, lab, embedded and protocol-analysis systems where this sniffer is deployed is routinely opened up to a non-root group or passed into a container. Choosing the higher-severity option between L and H, an ordinary unprivileged user with the device node is sufficient.\nUI:N - The attacker performs the `read()` themselves and needs no victim action; the overflow occurs as soon as a packet longer than the supplied buffer is dequeued. No mount, no file open by another user, no configuration change by an administrator is required.\nS:U - The out-of-bounds write lands inside the address space of the process that issued the `read()`, and the compromised resources belong to the same security authority as the vulnerable kernel component. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - `nosy_read()` returns a length greater than the requested `count`, so a caller following the standard read idiom consumes, prints, or logs memory located beyond its own buffer \u2014 an unbounded disclosure of adjacent process memory (heap pointers, keys, buffered data). The accompanying memory corruption is further leverageable to leak state from a privileged reader.\nI:H - Up to roughly 8 KB of externally supplied 1394 packet bytes are written past the end of the caller\u0027s stack or heap buffer, giving a large, content-controlled out-of-bounds write. Overwriting adjacent objects, saved registers, or function pointers in a nosy consumer that customarily runs as root yields control-flow hijack and arbitrary modification.\nA:H - The overflow reliably smashes adjacent memory and will SIGSEGV or abort the reading process (typically a root sniffer/logging daemon), and the copy can also fault mid-transfer leaving the buffer state inconsistent. Repeated triggering keeps the affected service permanently down."

Title
genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offline
Summary
In the Linux kernel, the following vulnerability has been resolved:
genirq/cpuhotplug, x86/vector: Prevent vector leak during CPU offline
The absence of IRQD_MOVE_PCNTXT prevents immediate effectiveness of
interrupt affinity reconfiguration via procfs. Instead, the change is
deferred until the next instance of the interrupt being triggered on the
original CPU.
When the interrupt next triggers on the original CPU, the new affinity is
enforced within __irq_move_irq(). A vector is allocated from the new CPU,
but the old vector on the original CPU remains and is not immediately
reclaimed. Instead, apicd->move_in_progress is flagged, and the reclaiming
process is delayed until the next trigger of the interrupt on the new CPU.
Upon the subsequent triggering of the interrupt on the new CPU,
irq_complete_move() adds a task to the old CPU's vector_cleanup list if it
remains online. Subsequently, the timer on the old CPU iterates over its
vector_cleanup list, reclaiming old vectors.
However, a rare scenario arises if the old CPU is outgoing before the
interrupt triggers again on the new CPU.
In that case irq_force_complete_move() is not invoked on the outgoing CPU
to reclaim the old apicd->prev_vector because the interrupt isn't currently
affine to the outgoing CPU, and irq_needs_fixup() returns false. Even
though __vector_schedule_cleanup() is later called on the new CPU, it
doesn't reclaim apicd->prev_vector; instead, it simply resets both
apicd->move_in_progress and apicd->prev_vector to 0.
As a result, the vector remains unreclaimed in vector_matrix, leading to a
CPU vector leak.
To address this issue, move the invocation of irq_force_complete_move()
before the irq_needs_fixup() call to reclaim apicd->prev_vector, if the
interrupt is currently or used to be affine to the outgoing CPU.
Additionally, reclaim the vector in __vector_schedule_cleanup() as well,
following a warning message, although theoretically it should never see
apicd->move_in_progress with apicd->prev_cpu pointing to an offline CPU.
