cxl/mbox: Break poison list loop on an empty payload
In the Linux kernel, the following vulnerability has been resolved:
cxl/mbox: Break poison list loop on an empty payload
A device that returns count == 0 with CXL_POISON_FLAG_MORE set on every
iteration never advances nr_records, so the max_errors guard never
trips and the do/while loops forever while holding poison.mutex. That
hangs the sysfs-triggered scan thread and blocks all subsequent poison
operations on the device. The existing "Protect against an uncleared
_FLAG_MORE" guard was intended to bound a misbehaving device but does
not cover the count == 0 case.
Stop the loop on an empty payload so a malfunctioning or malicious

hfsplus: validate thread record before delete key rebuild
In the Linux kernel, the following vulnerability has been resolved:
hfsplus: validate thread record before delete key rebuild
hfsplus_delete_cat() is called with str == NULL when the last open
reference to an unlinked HFS+ hardlink backing inode is closed. In that
case, the function finds the catalog thread by CNID and rebuilds the
catalog key from thread.nodeName.
That reconstruction path reads thread.nodeName.length directly from the
catalog B-tree into fd.search_key and then copies length * 2 bytes into
fd.search_key->cat.name.unicode. It does not first check that the found
record is a thread record or that its size matches the thread n

firmware: arm_scmi: Publish channel state before callbacks
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Publish channel state before callbacks
Transport setup can enable callbacks before the setup routine returns.
mailbox_chan_setup() registers the mailbox client with
mbox_request_channel(), and the mailbox controller startup path can enable
interrupt delivery before SCMI mailbox channel state has been published.
Similarly, smc_chan_setup() requests the optional A2P completion IRQ before
the SMC transport has made its cinfo pointer visible.
If a pending or spurious callback fires in those windows, the transport RX
callback can dereference a NULL transport

firmware: arm_scmi: Unregister device notifier before IDR teardown
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Unregister device notifier before IDR teardown
The requested-devices notifier looks up protocol fwnodes from the
active_protocols IDR. During remove, unregister the notifier before
releasing and destroying active_protocols so no notifier callback can race
with the IDR teardown.
Keep the bus notifier registered until after the protocol state is torn
down, matching the existing remove ordering for SCMI bus users.

firmware: arm_scmi: Quiesce notifications before teardown
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Quiesce notifications before teardown
scmi_notification_exit() clears and releases the notification instance,
but transport callbacks can still deliver incoming notifications until
the TX/RX channels are freed. During remove, an RX interrupt in that
window can enter scmi_notify() while notification state is being torn
down and then dereference freed memory. The same ordering exists on the
probe error path after notification initialization.
The notification late-init worker has a separate lifetime issue: protocol

firmware: arm_scmi: Clean up channels on setup failure
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Clean up channels on setup failure
scmi_channels_setup() can fail after the common BASE channel or earlier
protocol channels have already been registered in the TX/RX IDRs.
Route this failure through the existing channel cleanup label so the
transport channels, transport devices and IDR state created before the
failure are released before the probe error path frees the SCMI instance
ID.

firmware: arm_scmi: Free transport channel on IDR failure
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Free transport channel on IDR failure
If transport channel setup succeeds but the following IDR insertion fails,
the error path destroys the transport device and frees the channel info
without invoking the transport cleanup callback.
Call chan_free() before destroying the device so transport specific
resources such as IRQs, mailbox channels and mapped shared memory are
released consistently with the normal teardown path.

firmware: arm_scmi: Avoid IDR updates while cleaning channels
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Avoid IDR updates while cleaning channels
scmi_cleanup_channels() walks the TX/RX channel IDRs with
idr_for_each() to free transport resources and destroy the dedicated
transport devices before calling idr_destroy().
The destroy callback removed each entry from the same IDR being walked.
That is not needed for this cleanup path, and it is unsafe because
idr_for_each() has not advanced its radix-tree iterator while the
callback is running. Removing the current entry from the callback can
invalidate the iterator state. The callback also cannot be protecte

firmware: arm_scmi: Reject out of range DT protocol IDs
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Reject out of range DT protocol IDs
SCMI protocol IDs carried in message headers are limited by
MSG_PROTOCOL_ID_MASK. The DT parsing paths noticed protocol IDs
outside that range, but only logged an error and then kept processing
the invalid value.
That lets a malformed 32-bit DT reg value reach helpers which take a u8
protocol ID, where it can be truncated and/or treated as a different
protocol.
For channel setup, two different out-of-range values can also be used as
distinct IDR keys while aliasing the generated SCMI protocol identity.

firmware: arm_scmi: Drop handle on protocol bind failures
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Drop handle on protocol bind failures
The SCMI bus notifier acquires an SCMI handle when the driver core emits
BUS_NOTIFY_BIND_DRIVER, before invoking the protocol driver probe
callback. The protocol probe path only checks whether sdev->handle is
set.
If device_link_add() fails after the handle has been acquired, the
protocol device can still bind with a valid handle but without the
dependency link to the SCMI parent. A concurrent parent unbind can then
miss the child and tear down the SCMI instance while the child still
holds a handle into it.

In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Unwind TX receiver mailbox setup failure
mailbox_chan_setup() can request an additional unidirectional TX
receiver channel after successfully acquiring the primary channel. If
that second request fails, the function returns immediately and leaves
the primary channel allocated.
Unwind the primary mailbox channel before returning the error so probe
deferral or other setup failures do not leave the channel busy for later
probe attempts.
In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Fix SCMI device destroy lifetimes
scmi_child_dev_find() drops the reference returned by
device_find_child() before returning the scmi_device pointer. A
concurrent unregister can then release the device while the destroy path
is still using the returned pointer.
Make the lookup helper return the device_find_child() reference and keep
it until scmi_device_destroy() has finished unregistering the child.
Also split device_unregister() in __scmi_device_destroy() so the SCMI bus
ID is not made reusable until after device_del() has removed the old
scmi_dev.N

dax: read holder_ops once in dax_holder_notify_failure()
In the Linux kernel, the following vulnerability has been resolved:
dax: read holder_ops once in dax_holder_notify_failure()
dax_holder_notify_failure() reads dax_dev->holder_ops twice without
READ_ONCE() -- once for the NULL check and once for the indirect
notify_failure() call. A concurrent fs_put_dax() can clear holder_ops
between the two reads, so the check can observe a non-NULL pointer while
the call dereferences NULL. (kill_dax() also clears holder_ops, but only
after synchronize_srcu(), so it cannot race a reader that is inside
dax_read_lock(); fs_put_dax() does no such synchronization.)

irqchip/renesas-irqc: Fix generic interrupt chip leak on remove
In the Linux kernel, the following vulnerability has been resolved:
irqchip/renesas-irqc: Fix generic interrupt chip leak on remove
The driver allocates domain generic chips probe. However, on driver
removal, the generic chips are not automatically freed when the interrupt
domain is removed because the domain flags do not include
IRQ_DOMAIN_FLAG_DESTROY_GC.
This causes both the domain generic chips structure and the associated
generic chips to be leaked. Additionally, the generic chips remain on the
global list and may later be accessed by generic interrupt chip suspend,
resume, or shutdown callbacks after the driver has been removed,

drm/bridge: tc358767: clamp the reported AUX read size to the request
In the Linux kernel, the following vulnerability has been resolved:
drm/bridge: tc358767: clamp the reported AUX read size to the request
tc_aux_transfer() clamps an AUX read to the payload limit:
size_t size = min_t(size_t, DP_AUX_MAX_PAYLOAD_BYTES - 1, msg->size);
After the transfer it replaces size with the byte count the controller
reports in AUX_BYTES:
if (size)
size = FIELD_GET(AUX_BYTES, auxstatus);
AUX_BYTES is GENMASK(15, 8), so it can be up to 255. Nothing clamps it
back to the request. tc_aux_read_data() reads that many bytes into the
16-byte auxrdata stack buffer, then copies them into the caller buffer. A

The loop counter 'count' was declared as u8 while num_pc is u32.
If firmware advertises more than 255 PC entries the counter wraps

In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: fix off-by-one in TXF key sanitiser
iwl_mvm_frob_txf_key_iter() tracks the last matched byte position
in loop variable 'i'. When a full key match is found (match ==
keylen), 'i' points at the last byte of the matched key. The
memset start offset should therefore be i + 1 - keylen, not
i - keylen; the current code zeroes one byte before the match
and leaves the final key byte un-sanitised.

gpu: host1x: Avoid stack over-read in debug output helpers
In the Linux kernel, the following vulnerability has been resolved:
gpu: host1x: Avoid stack over-read in debug output helpers
host1x_debug_output() and host1x_debug_cont() used vsnprintf(), which
returns the length the formatted string would have reached with an
unbounded buffer. That return value was passed straight to o->fn as
the number of bytes to emit.
This could cause a read past end of the output buffer if a call to
host1x_debug_* produced a string longer than 256 bytes. This only
affected the debugfs files as the printk debug sink ignores the
number of bytes. In practice, this is very unlikely to occur.
