The actual device uninit usually happens on a separate thread
scheduled after this code runs, but there is no guarantee of order
of thread execution, so this could be a problem.  There's no
actual need to clear the client_id at this point, so simply
remove the offending code.

CVE-2025-37918 Bluetooth: btusb: avoid NULL pointer dereference in skb_dequeue()
In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: btusb: avoid NULL pointer dereference in skb_dequeue()

A NULL pointer dereference can occur in skb_dequeue() when processing a
QCA firmware crash dump on WCN7851 (0489:e0f3).

[ 93.672166] Bluetooth: hci0: ACL memdump size(589824)

[ 93.672475] BUG: kernel NULL pointer dereference, address: 0000000000000008
[ 93.672517] Workqueue: hci0 hci_devcd_rx [bluetooth]
[ 93.672598] RIP: 0010:skb_dequeue+0x50/0x80

The issue stems from handle_dump_pkt_qca() returning 0 even when a dump
packet is successfully processed. This is because it incorrectly
forwards the return value of hci_devcd_init() (which returns 0 on
success). As a result, the caller (btusb_recv_acl_qca() or
btusb_recv_evt_qca()) assumes the packet was not handled and passes it
to hci_recv_frame(), leading to premature kfree() of the skb.

Later, hci_devcd_rx() attempts to dequeue the same skb from the dump
queue, resulting in a NULL pointer dereference.

Fix this by:
1. Making handle_dump_pkt_qca() return 0 on success and negative errno
   on failure, consistent with kernel conventions.
2. Splitting dump packet detection into separate functions for ACL
   and event packets for better structure and readability.

This ensures dump packets are properly identified and consumed, avoiding
double handling and preventing NULL pointer access.

CVE-2025-37920 xsk: Fix race condition in AF_XDP generic RX path
In the Linux kernel, the following vulnerability has been resolved:

xsk: Fix race condition in AF_XDP generic RX path

Move rx_lock from xsk_socket to xsk_buff_pool.
Fix synchronization for shared umem mode in
generic RX path where multiple sockets share
single xsk_buff_pool.

RX queue is exclusive to xsk_socket, while FILL
queue can be shared between multiple sockets.
This could result in race condition where two
CPU cores access RX path of two different sockets
sharing the same umem.

Protect both queues by acquiring spinlock in shared
xsk_buff_pool.

Lock contention may be minimized in the future by some
per-thread FQ buffering.

It's safe and necessary to move spin_lock_bh(rx_lock)
after xsk_rcv_check():
* xs->pool and spinlock_init is synchronized by
  xsk_bind() -> xsk_is_bound() memory barriers.
* xsk_rcv_check() may return true at the moment
  of xsk_release() or xsk_unbind_dev(),
  however this will not cause any data races or
  race conditions. xsk_unbind_dev() removes xdp
  socket from all maps and waits for completion
  of all outstanding rx operations. Packets in
  RX path will either complete safely or drop.

CVE-2025-37921 vxlan: vnifilter: Fix unlocked deletion of default FDB entry
In the Linux kernel, the following vulnerability has been resolved:

vxlan: vnifilter: Fix unlocked deletion of default FDB entry

When a VNI is deleted from a VXLAN device in 'vnifilter' mode, the FDB
entry associated with the default remote (assuming one was configured)
is deleted without holding the hash lock. This is wrong and will result
in a warning [1] being generated by the lockdep annotation that was
added by commit ebe642067455 ("vxlan: Create wrappers for FDB lookup").

Reproducer:

 # ip link add vx0 up type vxlan dstport 4789 external vnifilter local 192.0.2.1
 # bridge vni add vni 10010 remote 198.51.100.1 dev vx0
 # bridge vni del vni 10010 dev vx0

Fix by acquiring the hash lock before the deletion and releasing it
afterwards. Blame the original commit that introduced the issue rather
than the one that exposed it.

This happens when 'clear_inode()' makes an attempt to finalize an underlying
JFS inode of unknown type. According to JFS layout description from
https://jfs.sourceforge.net/project/pub/jfslayout.pdf, inode types from 5 to
15 are reserved for future extensions and should not be encountered on a valid
filesystem. So add an extra check for valid inode type in 'copy_from_dinode()'.

In the Linux kernel, the following vulnerability has been resolved:

iommu/amd: Fix potential buffer overflow in parse_ivrs_acpihid

There is a string parsing logic error which can lead to an overflow of hid
or uid buffers. Comparing ACPIID_LEN against a total string length doesn't
take into account the lengths of individual hid and uid buffers so the
check is insufficient in some cases. For example if the length of hid
string is 4 and the length of the uid string is 260, the length of str
will be equal to ACPIID_LEN + 1 but uid string will overflow uid buffer
which size is 256.

The same applies to the hid string with length 13 and uid string with
length 250.

Check the length of hid and uid strings separately to prevent
buffer overflow.

In the Linux kernel, the following vulnerability has been resolved:

arm64: errata: Add missing sentinels to Spectre-BHB MIDR arrays

Commit a5951389e58d ("arm64: errata: Add newer ARM cores to the
spectre_bhb_loop_affected() lists") added some additional CPUs to the
Spectre-BHB workaround, including some new arrays for designs that
require new 'k' values for the workaround to be effective.

Unfortunately, the new arrays omitted the sentinel entry and so
is_midr_in_range_list() will walk off the end when it doesn't find a
match. With UBSAN enabled, this leads to a crash during boot when
is_midr_in_range_list() is inlined (which was more common prior to
c8c2647e69be ("arm64: Make  _midr_in_range_list() an exported

In the Linux kernel, the following vulnerability has been resolved:

drm/nouveau: Fix WARN_ON in nouveau_fence_context_kill()

Nouveau is mostly designed in a way that it's expected that fences only
ever get signaled through nouveau_fence_signal(). However, in at least
one other place, nouveau_fence_done(), can signal fences, too. If that
happens (race) a signaled fence remains in the pending list for a while,
until it gets removed by nouveau_fence_update().

Should nouveau_fence_context_kill() run in the meantime, this would be
a bug because the function would attempt to set an error code on an
already signaled fence.

Have nouveau_fence_context_kill() check for a fence being signaled.

CVE-2025-37931 btrfs: adjust subpage bit start based on sectorsize
In the Linux kernel, the following vulnerability has been resolved:

btrfs: adjust subpage bit start based on sectorsize

When running machines with 64k page size and a 16k nodesize we started
seeing tree log corruption in production.  This turned out to be because
we were not writing out dirty blocks sometimes, so this in fact affects
all metadata writes.

When writing out a subpage EB we scan the subpage bitmap for a dirty
range.  If the range isn't dirty we do

	bit_start++;

to move onto the next bit.  The problem is the bitmap is based on the
number of sectors that an EB has.  So in this case, we have a 64k
pagesize, 16k nodesize, but a 4k sectorsize.  This means our bitmap is 4
bits for every node.  With a 64k page size we end up with 4 nodes per
page.

To make this easier this is how everything looks

[0         16k       32k       48k     ] logical address
[0         4         8         12      ] radix tree offset
[               64k page               ] folio
[ 16k eb ][ 16k eb ][ 16k eb ][ 16k eb ] extent buffers
[ | | | |  | | | |   | | | |   | | | | ] bitmap

Now we use all of our addressing based on fs_info->sectorsize_bits, so
as you can see the above our 16k eb->start turns into radix entry 4.

When we find a dirty range for our eb, we correctly do bit_start +=
sectors_per_node, because if we start at bit 0, the next bit for the
next eb is 4, to correspond to eb->start 16k.

However if our range is clean, we will do bit_start++, which will now
put us offset from our radix tree entries.

In our case, assume that the first time we check the bitmap the block is
not dirty, we increment bit_start so now it == 1, and then we loop
around and check again.  This time it is dirty, and we go to find that
start using the following equation

	start = folio_start + bit_start * fs_info->sectorsize;

so in the case above, eb->start 0 is now dirty, and we calculate start
as

	0 + 1 * fs_info->sectorsize = 4096
	4096 >> 12 = 1

Now we're looking up the radix tree for 1, and we won't find an eb.
What's worse is now we're using bit_start == 1, so we do bit_start +=
sectors_per_node, which is now 5.  If that eb is dirty we will run into
the same thing, we will look at an offset that is not populated in the
radix tree, and now we're skipping the writeout of dirty extent buffers.

The best fix for this is to not use sectorsize_bits to address nodes,
but that's a larger change.  Since this is a fs corruption problem fix
it simply by always using sectors_per_node to increment the start bit.

CVE-2025-37932 sch_htb: make htb_qlen_notify() idempotent
In the Linux kernel, the following vulnerability has been resolved:

sch_htb: make htb_qlen_notify() idempotent

htb_qlen_notify() always deactivates the HTB class and in fact could
trigger a warning if it is already deactivated. Therefore, it is not
idempotent and not friendly to its callers, like fq_codel_dequeue().

Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers'
life.

CVE-2025-37933 octeon_ep: Fix host hang issue during device reboot
In the Linux kernel, the following vulnerability has been resolved:

octeon_ep: Fix host hang issue during device reboot

When the host loses heartbeat messages from the device,
the driver calls the device-specific ndo_stop function,
which frees the resources. If the driver is unloaded in
this scenario, it calls ndo_stop again, attempting to free
resources that have already been freed, leading to a host
hang issue. To resolve this, dev_close should be called
instead of the device-specific stop function.dev_close
internally calls ndo_stop to stop the network interface
and performs additional cleanup tasks. During the driver
unload process, if the device is already down, ndo_stop
is not called.

CVE-2025-37934 ASoC: simple-card-utils: Fix pointer check in graph_util_parse_link_direction
In the Linux kernel, the following vulnerability has been resolved:

ASoC: simple-card-utils: Fix pointer check in graph_util_parse_link_direction

Actually check if the passed pointers are valid, before writing to them.
This also fixes a USBAN warning:
UBSAN: invalid-load in ../sound/soc/fsl/imx-card.c:687:25
load of value 255 is not a valid value for type '_Bool'

This is because playback_only is uninitialized and is not written to, as
the playback-only property is absent.

CVE-2025-37935 net: ethernet: mtk_eth_soc: fix SER panic with 4GB+ RAM
In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: mtk_eth_soc: fix SER panic with 4GB+ RAM

If the mtk_poll_rx() function detects the MTK_RESETTING flag, it will
jump to release_desc and refill the high word of the SDP on the 4GB RFB.
Subsequently, mtk_rx_clean will process an incorrect SDP, leading to a
panic.

Add patch from MediaTek's SDK to resolve this.
