Title
net: fix fanout UAF in packet_release() via NETDEV_UP race
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: fix fanout UAF in packet_release() via NETDEV_UP race
`packet_release()` has a race window where `NETDEV_UP` can re-register a
socket into a fanout group's `arr[]` array. The re-registration is not
cleaned up by `fanout_release()`, leaving a dangling pointer in the fanout
array.
`packet_release()` does NOT zero `po->num` in its `bind_lock` section.
After releasing `bind_lock`, `po->num` is still non-zero and `po->ifindex`
still matches the bound device. A concurrent `packet_notifier(NETDEV_UP)`
that already found the socket in `sklist` can re-register the hook.
For fanout sockets, this re-registration calls `__fanout_link(sk, po)`
which adds the socket back into `f->arr[]` and increments `f->num_members`,
but does NOT increment `f->sk_ref`.
The fix sets `po->num` to zero in `packet_release` while `bind_lock` is
held to prevent NETDEV_UP from linking, preventing the race window.
This bug was found following an additional audit with Claude Code based
on CVE-2025-38617.

Title
net/smc: fix double-free of smc_spd_priv when tee() duplicates splice pipe buffer
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/smc: fix double-free of smc_spd_priv when tee() duplicates splice pipe buffer
smc_rx_splice() allocates one smc_spd_priv per pipe_buffer and stores
the pointer in pipe_buffer.private. The pipe_buf_operations for these
buffers used .get = generic_pipe_buf_get, which only increments the page
reference count when tee(2) duplicates a pipe buffer. The smc_spd_priv
pointer itself was not handled, so after tee() both the original and the
cloned pipe_buffer share the same smc_spd_priv *.
When both pipes are subsequently released, smc_rx_pipe_buf_release() is
called twice against the same object:
1st call: kfree(priv) sock_put(sk) smc_rx_update_cons() [correct]
2nd call: kfree(priv) sock_put(sk) smc_rx_update_cons() [UAF]
KASAN reports a slab-use-after-free in smc_rx_pipe_buf_release(), which
then escalates to a NULL-pointer dereference and kernel panic via
smc_rx_update_consumer() when it chases the freed priv->smc pointer:

Kernel panic - not syncing: Fatal exception
Beyond the memory-safety problem, duplicating an SMC splice buffer is
semantically questionable: smc_rx_update_cons() would advance the
consumer cursor twice for the same data, corrupting receive-window
accounting. A refcount on smc_spd_priv could fix the double-free, but
the cursor-accounting issue would still need to be addressed separately.
The .get callback is invoked by both tee(2) and splice_pipe_to_pipe()
for partial transfers; both will now return -EFAULT. Users who need
to duplicate SMC socket data must use a copy-based read path.

Following kernel CVSS guidance, this memory corruption can support information disclosure primitives.\nI:H - The duplicate release can lead to allocator corruption and attacker-influenced dereferences through the freed smc_spd_priv contents. Following kernel CVSS guidance for UAF/double-free memory corruption, arbitrary write or control-flow compromise is a defensible impact.\nA:H - The reported failure includes KASAN slab-use-after-free followed by NULL pointer dereference and kernel panic in smc_rx_update_consumer().

Title
net: openvswitch: Avoid releasing netdev before teardown completes
Summary
In the Linux kernel, the following vulnerability has been resolved:
net: openvswitch: Avoid releasing netdev before teardown completes
The patch cited in the Fixes tag below changed the teardown code for
OVS ports to no longer unconditionally take the RTNL. After this change,
the netdev_destroy() callback can proceed immediately to the call_rcu()
invocation if the IFF_OVS_DATAPATH flag is already cleared on the
netdev.
The ovs_netdev_detach_dev() function clears the flag before completing
the unregistration, and if it gets preempted after clearing the flag (as
can happen on an -rt kernel), netdev_destroy() can complete and the
device can be freed before the unregistration completes. This leads to a
splat like:

Title
nfc: nci: fix circular locking dependency in nci_close_device
Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: nci: fix circular locking dependency in nci_close_device
nci_close_device() flushes rx_wq and tx_wq while holding req_lock.
This causes a circular locking dependency because nci_rx_work()
running on rx_wq can end up taking req_lock too:
nci_rx_work -> nci_rx_data_packet -> nci_data_exchange_complete
-> __sk_destruct -> rawsock_destruct -> nfc_deactivate_target
-> nci_deactivate_target -> nci_request -> mutex_lock(&ndev->req_lock)
Move the flush of rx_wq after req_lock has been released.
This should safe (I think) because NCI_UP has already been cleared
and the transport is closed, so the work will see it and return
-ENETDOWN.
NIPA has been hitting this running the nci selftest with a debug
kernel on roughly 4% of the runs.

Title
Bluetooth: L2CAP: Validate PDU length before reading SDU length in l2cap_ecred_data_rcv()
Summary
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: Validate PDU length before reading SDU length in l2cap_ecred_data_rcv()
l2cap_ecred_data_rcv() reads the SDU length field from skb->data using
get_unaligned_le16() without first verifying that skb contains at least
L2CAP_SDULEN_SIZE (2) bytes. When skb->len is less than 2, this reads
past the valid data in the skb.
The ERTM reassembly path correctly calls pskb_may_pull() before reading
the SDU length (l2cap_reassemble_sdu, L2CAP_SAR_START case). Apply the
same validation to the Enhanced Credit Based Flow Control data path.
Severity
No CVSS data available.

Issue is that pfkey_send_migrate() does not check old/new families,
and that set_ipsecrequest() @family argument was truncated,
thus possibly overfilling the skb.
Validate families early, do not wait set_ipsecrequest().

Title
esp: fix skb leak with espintcp and async crypto
Summary
In the Linux kernel, the following vulnerability has been resolved:
esp: fix skb leak with espintcp and async crypto
When the TX queue for espintcp is full, esp_output_tail_tcp will
return an error and not free the skb, because with synchronous crypto,
the common xfrm output code will drop the packet for us.
With async crypto (esp_output_done), we need to drop the skb when
esp_output_tail_tcp returns an error.

Title
btrfs: set BTRFS_ROOT_ORPHAN_CLEANUP during subvol create
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: set BTRFS_ROOT_ORPHAN_CLEANUP during subvol create
We have recently observed a number of subvolumes with broken dentries.
ls-ing the parent dir looks like:
drwxrwxrwt 1 root root 16 Jan 23 16:49 .
drwxr-xr-x 1 root root 24 Jan 23 16:48 ..
d????????? ? ? ? ? ? broken_subvol
and similarly stat-ing the file fails.
In this state, deleting the subvol fails with ENOENT, but attempting to
create a new file or subvol over it errors out with EEXIST and even
aborts the fs. Which leaves us a bit stuck.
dmesg contains a single notable error message reading:
"could not do orphan cleanup -2"
2 is ENOENT and the error comes from the failure handling path of
btrfs_orphan_cleanup(), with the stack leading back up to
btrfs_lookup().
btrfs_lookup
btrfs_lookup_dentry
btrfs_orphan_cleanup // prints that message and returns -ENOENT
After some detailed inspection of the internal state, it became clear
that:
- there are no orphan items for the subvol
- the subvol is otherwise healthy looking, it is not half-deleted or
anything, there is no drop progress, etc.
- the subvol was created a while ago and does the meaningful first
btrfs_orphan_cleanup() call that sets BTRFS_ROOT_ORPHAN_CLEANUP much
later.
- after btrfs_orphan_cleanup() fails, btrfs_lookup_dentry() returns -ENOENT,
which results in a negative dentry for the subvolume via
d_splice_alias(NULL, dentry), leading to the observed behavior. The
bug can be mitigated by dropping the dentry cache, at which point we
can successfully delete the subvolume if we want.
i.e.,
btrfs_lookup()
btrfs_lookup_dentry()
if (!sb_rdonly(inode->vfs_inode)->vfs_inode)
btrfs_orphan_cleanup(sub_root)
test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP)
btrfs_search_slot() // finds orphan item for inode N
...
prints "could not do orphan cleanup -2"
if (inode == ERR_PTR(-ENOENT))
inode = NULL;
return d_splice_alias(NULL, dentry) // NEGATIVE DENTRY for valid subvolume
btrfs_orphan_cleanup() does test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP)
on the root when it runs, so it cannot run more than once on a given
root, so something else must run concurrently. However, the obvious
routes to deleting an orphan when nlinks goes to 0 should not be able to
run without first doing a lookup into the subvolume, which should run
btrfs_orphan_cleanup() and set the bit.
The final important observation is that create_subvol() calls
d_instantiate_new() but does not set BTRFS_ROOT_ORPHAN_CLEANUP, so if
the dentry cache gets dropped, the next lookup into the subvolume will
make a real call into btrfs_orphan_cleanup() for the first time. This
opens up the possibility of concurrently deleting the inode/orphan items
but most typical evict() paths will be holding a reference on the parent
dentry (child dentry holds parent->d_lockref.count via dget in
d_alloc(), released in __dentry_kill()) and prevent the parent from
being removed from the dentry cache.
The one exception is delayed iputs. Ordered extent creation calls
igrab() on the inode. If the file is unlinked and closed while those
refs are held, iput() in __dentry_kill() decrements i_count but does
not trigger eviction (i_count > 0). The child dentry is freed and the
subvol dentry's d_lockref.count drops to 0, making it evictable while
the inode is still alive.
Since there are two races (the race between writeback and unlink and
the race between lookup and delayed iputs), and there are too many moving
parts, the following three diagrams show the complete picture.
(Only the second and third are races)
Phase 1:
Create Subvol in dentry cache without BTRFS_ROOT_ORPHAN_CLEANUP set
btrfs_mksubvol()
lookup_one_len()
__lookup_slow()
d_alloc_parallel()
__d_alloc() // d_lockref.count = 1
create_subvol(dentry)
// doesn't touch the bit..
d_instantiate_new(dentry, inode) // dentry in cache with d_lockref.c

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: set BTRFS_ROOT_ORPHAN_CLEANUP during subvol create\n\nWe have recently observed a number of subvolumes with broken dentries.\nls-ing the parent dir looks like:\n\ndrwxrwxrwt 1 root root 16 Jan 23 16:49 .\ndrwxr-xr-x 1 root root 24 Jan 23 16:48 ..\nd????????? ? ? ? ? ? broken_subvol\n\nand similarly stat-ing the file fails.\n\nIn this state, deleting the subvol fails with ENOENT, but attempting to\ncreate a new file or subvol over it errors out with EEXIST and even\naborts the fs. Which leaves us a bit stuck.\n\ndmesg contains a single notable error message reading:\n\"could not do orphan cleanup -2\"\n\n2 is ENOENT and the error comes from the failure handling path of\nbtrfs_orphan_cleanup(), with the stack leading back up to\nbtrfs_lookup().\n\nbtrfs_lookup\nbtrfs_lookup_dentry\nbtrfs_orphan_cleanup // prints that message and returns -ENOENT\n\nAfter some detailed inspection of the internal state, it became clear\nthat:\n- there are no orphan items for the subvol\n- the subvol is otherwise healthy looking, it is not half-deleted or\n anything, there is no drop progress, etc.\n- the subvol was created a while ago and does the meaningful first\n btrfs_orphan_cleanup() call that sets BTRFS_ROOT_ORPHAN_CLEANUP much\n later.\n- after btrfs_orphan_cleanup() fails, btrfs_lookup_dentry() returns -ENOENT,\n which results in a negative dentry for the subvolume via\n d_splice_alias(NULL, dentry), leading to the observed behavior. The\n bug can be mitigated by dropping the dentry cache, at which point we\n can successfully delete the subvolume if we want.\n\ni.e.,\nbtrfs_lookup()\n btrfs_lookup_dentry()\n if (!sb_rdonly(inode-\u003evfs_inode)-\u003evfs_inode)\n btrfs_orphan_cleanup(sub_root)\n test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP)\n btrfs_search_slot() // finds orphan item for inode N\n ...\n prints \"could not do orphan cleanup -2\"\n if (inode == ERR_PTR(-ENOENT))\n inode = NULL;\n return d_splice_alias(NULL, dentry) // NEGATIVE DENTRY for valid subvolume\n\nbtrfs_orphan_cleanup() does test_and_set_bit(BTRFS_ROOT_ORPHAN_CLEANUP)\non the root when it runs, so it cannot run more than once on a given\nroot, so something else must run concurrently. However, the obvious\nroutes to deleting an orphan when nlinks goes to 0 should not be able to\nrun without first doing a lookup into the subvolume, which should run\nbtrfs_orphan_cleanup() and set the bit.\n\nThe final important observation is that create_subvol() calls\nd_instantiate_new() but does not set BTRFS_ROOT_ORPHAN_CLEANUP, so if\nthe dentry cache gets dropped, the next lookup into the subvolume will\nmake a real call into btrfs_orphan_cleanup() for the first time. This\nopens up the possibility of concurrently deleting the inode/orphan items\nbut most typical evict() paths will be holding a reference on the parent\ndentry (child dentry holds parent-\u003ed_lockref.count via dget in\nd_alloc(), released in __dentry_kill()) and prevent the parent from\nbeing removed from the dentry cache.\n\nThe one exception is delayed iputs. Ordered extent creation calls\nigrab() on the inode. If the file is unlinked and closed while those\nrefs are held, iput() in __dentry_kill() decrements i_count but does\nnot trigger eviction (i_count \u003e 0). The child dentry is freed and the\nsubvol dentry\u0027s d_lockref.count drops to 0, making it evictable while\nthe inode is still alive.\n\nSince there are two races (the race between writeback and unlink and\nthe race between lookup and delayed iputs), and there are too many moving\nparts, the following three diagrams show the complete picture.\n(Only the second and third are races)\n\nPhase 1:\nCreate Subvol in dentry cache without BTRFS_ROOT_ORPHAN_CLEANUP set\n\nbtrfs_mksubvol()\n lookup_one_len()\n __lookup_slow()\n d_alloc_parallel()\n __d_alloc() // d_lockref.count = 1\n create_subvol(dentry)\n // doesn\u0027t touch the bit..\n d_instantiate_new(dentry, inode) // dentry in cache with d_lockref.c\n---truncated---"

Title
HID: apple: avoid memory leak in apple_report_fixup()
Summary
In the Linux kernel, the following vulnerability has been resolved:
HID: apple: avoid memory leak in apple_report_fixup()
The apple_report_fixup() function was returning a
newly kmemdup()-allocated buffer, but never freeing it.
The caller of report_fixup() does not take ownership of the returned
pointer, but it *is* permitted to return a sub-portion of the input
rdesc, whose lifetime is managed by the caller.
Severity
No CVSS data available.
