binder_transaction() bounds the scatter-gather buffer area with
sg_buf_end_offset and subtracts the aligned LSM context size because
the secctx is written at the tail of that area. The subtraction reads
lsmctx.len, but that field has already been cleared by the time the
line runs:
security_secid_to_secctx(secid, &lsmctx) /* lsmctx.len set */
lsmctx_aligned_size = ALIGN(lsmctx.len, sizeof(u64))
extra_buffers_size += lsmctx_aligned_size
...
security_release_secctx(&lsmctx) /* memset zeroes len */
...
sg_buf_end_offset = sg_buf_offset + extra_buffers_size
- ALIGN(lsmctx.len, sizeof(u64)) /* ALIGN(0,8) */
security_release_secctx() does memset(cp, 0, sizeof(*cp)), so lsmctx.len
reads back as 0 and the subtraction contributes nothing, leaving
sg_buf_end_offset too large by the aligned secctx size on every
transaction to a txn_security_ctx node.
Each BINDER_TYPE_PTR object then derives buf_left = sg_buf_end_offset -
sg_buf_offset as the sole upper bound on its copy, so the inflated end
offset lets the copy run into the bytes that already hold the secctx.
The aligned size must therefore be cached before release rather than
re-read from the now-cleared field. Fix by caching it in
lsmctx_aligned_size at function scope when it is first computed and
subtracting lsmctx_aligned_size instead of re-reading lsmctx.len after
release. Reuse the same value for the earlier buf_offset computation.

This code currently copies the ExtendedError struct to the stack,
modifies the copy, and then doesn't modify the original. Thus, fix it.
Furthermore, errors when replying must be delivered directly to the

GUE private flags can indicate that remote checksum offload metadata is
present. The private flags field itself is accounted for by
guehdr_flags_len(), but guehdr_priv_flags_len() currently returns 0 even
when GUE_PFLAG_REMCSUM is set.
This lets a packet with only the private flags field pass
validate_gue_flags(), after which gue_remcsum() and gue_gro_remcsum()
read the missing REMCSUM start/offset fields from the following bytes.
Account for GUE_PLEN_REMCSUM when GUE_PFLAG_REMCSUM is present so that
malformed packets are rejected during option validation.

ASoC: Fixes for v7.2
A fairly standard set of driver specific fixes and quirks that have come
in since the merge window, plus a MAINTAINERS update. The tas675x

Pull mod_devicetable.h header split from Uwe Kleine-König:
"Split <linux/mod_devicetable.h> in per subsystem headers
<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result of this mixture of different and unrelated subsystem
details is that even when touching an obscure device id struct most of
the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per
subsystem headers and only including what is really needed reduces the
amount of needed recompilation.
This split is implemented in the first commit and then after some
preparatory work in the following commits, the last two replace
includes of <linux/mod_devicetable.h> by the actually needed more
specific headers.
There are still a few instances left, but the ones with high impact
(that is in headers that are used a lot) and the easy ones (.c files)
are handled. These remaining includes will be addressed during the
next merge window"

otx2_init_hw_resources() initializes SQ aura and pool resources before
several later setup steps. On failure, err_free_sq_ptrs only frees SQB
pages, leaving the per-SQ sqb_ptrs arrays behind.
Use otx2_free_sq_res() for the SQ unwind path and let it free sqb_ptrs
even when sq->sqe has not been allocated yet.
The bug was first flagged by an experimental analysis tool we are
developing for kernel memory-management bugs while analyzing
v6.13-rc1. The tool is still under development and is not yet publicly
available. Manual inspection confirms that the bug is still
present in v7.1.1.
An x86_64 allyesconfig build showed no new warnings. As we do not have an
OcteonTX2 PF device and the corresponding AF mailbox setup to test with,
no runtime testing was able to be performed.

For an even packet_len, net1080_rx_fixup() reads the pad byte at

down, and packet_len is only bounded against NC_MAX_PACKET. A malicious

; some of them are widely used headers. To stop mixing up different and

Platform drivers can define an array containing the supported device
variants to be assigned to the struct platform_driver's .id_table.
While a forward declaration of struct platform_device_id is technically
enough to make the driver self-contained, it's reasonable to provide the
(very lightweight) data type definition for that array in

with an id-table.
Note that currently <linux/device.h> transitively includes

that include is planned to be replaced by a tighter set of includes that

device_driver
struct device_driver contains pointers of type struct of_device_id* and
struct acpi_device_id* but doesn't ensure these are defined. To make the
header self-contained add the (very lightweight) includes that contain
the respective definitions.

The driver uses several symbols and structs defined in that header. The
header is currently included transitively via
"vip.h" ->
<media/v4l2-ctrls.h> ->
<media/media-request.h> ->
<media/media-device.h> ->
<linux/platform_device.h>
which seems to be on the lower end of the scale between random and

<linux/mod_devicetable.h> is included transitively in nearly every
driver in an x86_64 allmodconfig build of v7.1:
$ find drivers -name \*.o -not -name \*.mod.o | wc -l
21330
$ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
17038
The result is that even when touching an obscure device id struct most
of the kernel needs to be recompiled. Given that each driver typically
only needs one or two of these structures, splitting into per subsystem
headers and only including what is really needed reduces the amount of
needed recompilation.
Implement the first step and define each device id struct in a separate
header (together with its associated #defines).
<linux/mod_devicetable.h> is modified to include all the new headers to
continue to provide the same symbols.
Several headers currently include <linux/mod_devicetable.h>, those that
are most lukrative to include only their subsystem headers only are:
$ git -C source grep -l mod_devicetable.h include/linux | while read h; do echo -n "$h:"; find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l $h | wc -l; done | sort -t: -k2 -n -r | head

include/linux/usb.h:1222
include/linux/input.h:1205
include/linux/mdio.h:835
include/linux/phy.h:733
struct cpu_feature isn't really a device_id struct. That is kept in
<linux/mod_devicetable.h> for now.

The function ata_scsi_rbuf_fill() is used to copy the response of
emulated SCSI commands from ata_scsi_rbuf to the SCSI command's
scatterlist.
Currently, sg_copy_from_buffer() is called with the size argument
set to ATA_SCSI_RBUF_SIZE (2048 bytes). Since ata_scsi_rbuf is
zeroed out before the simulation actor is invoked, copying the
full buffer size causes the remainder of the SCSI command's
transfer buffer (beyond the actual response length 'len') to be
overwritten with zeroes. This clobbers any pre-existing sentinel
values or data in the caller's buffer tail, even though the
correct residual count is reported via scsi_set_resid().
Fix this by passing the actual response length 'len' as the copy
size to sg_copy_from_buffer(), ensuring that the tail of the
caller's buffer remains untouched. Also, add a defensive check
to ensure that the actor does not return a length exceeding the
static buffer capacity. If this occurs, trigger a WARN_ON(),
fail the command with an aborted command error, and return
immediately without copying any data.
The fix was tested by invoking an SCSI SG_IO INQUIRY on
an ATA disk on vanilla build, and build with the fix. Confirmed
that the input buffer's tail end remains unmodified with the fix.

gemini_sata_bridge_init() prepares and enables both SATA PCLKs, then
disables them again while keeping the clocks prepared for later bridge
start and stop operations. If gemini_setup_ide_pins() fails after that,
gemini_sata_probe() returns directly and skips the existing
out_unprep_clk unwind path.
Route the IDE pinctrl failure through out_unprep_clk so the clocks
prepared by gemini_sata_bridge_init() are unprepared before probe

ata_dev_config_cpr() takes the number of range descriptors from buf[0]
of the concurrent positioning ranges log (up to 255), which the device
reports independently of the log size in the GPL directory. The count is
then walked at a fixed 32-byte stride in two places with no bound: the
log read here, and the INQUIRY VPD page B9h emitter, which writes one
descriptor per range into the fixed 2048-byte ata_scsi_rbuf. A device
reporting a count larger than its own log overflows the read buffer (up
to 7704 bytes past a 512-byte slab), and a count above 62 overflows the
response buffer on the emit side.
Bound the count once, on probe, against both the log the device returned
and the number of descriptors the VPD B9h response buffer can hold
(ATA_DEV_MAX_CPR, derived from the rbuf size). Reject an out-of-range
count with a warning; this keeps the emitter in bounds with no separate
change there.

In ATH11K_QMI_EVENT_FW_READY, ATH11K_FLAG_REGISTERED is set
unconditionally even when ath11k_core_qmi_firmware_ready() fails.
This leaves the driver in an inconsistent state where
initialization is considered complete although the firmware ready
handling did not finish successfully. During the subsequent SSR,
the driver enters the restart path based on this incorrect state
and dereferences uninitialized srng members, resulting in a NULL
pointer dereference.
Call trace:
ath11k_hal_srng_access_begin+0xc/0x60 [ath11k] (P)
ath11k_ce_cleanup_pipes+0x17c/0x180 [ath11k]
ath11k_core_restart+0x40/0x168 [ath11k]
Fix this by:
- skipping firmware_ready if ATH11K_FLAG_REGISTERED is already set
- setting ATH11K_FLAG_REGISTERED only when firmware_ready succeeds
- setting ATH11K_FLAG_QMI_FAIL and aborting the FW_READY handling
on error

The aggr_reset_state() function uses timer_delete() (non-synchronous)
for the aggregation timer before proceeding to delete TID state and
before the structure is freed by callers like aggr_module_destroy().
If the timer callback (aggr_timeout) is executing when aggr_reset_state()
is called, the callback will continue to access aggr_conn fields like
rx_tid[] and stat[] which may be freed immediately after by
kfree(aggr_info->aggr_conn) in aggr_module_destroy().
Additionally, the timer callback can re-arm itself via mod_timer() while
aggr_reset_state() is running, creating a more complex race condition.
Use timer_delete_sync() instead to ensure any running timer callback
has completed before returning.

ath9k_hif_request_firmware() re-arms an asynchronous firmware load via
request_firmware_nowait(), passing hif_dev as the completion context, and
then still dereferences hif_dev:
dev_info(&hif_dev->udev->dev, "ath9k_htc: Firmware %s requested\n",
hif_dev->fw_name);
The re-armed callback ath9k_hif_usb_firmware_cb() runs on the "events"
workqueue and, when the firmware is missing, walks the retry chain into
ath9k_hif_usb_firmware_fail() -> complete_all(&hif_dev->fw_done). That
releases the wait_for_completion(&hif_dev->fw_done) in a concurrent
ath9k_hif_usb_disconnect(), which then kfree()s hif_dev. The trailing
dev_info() in the frame that re-armed the request can therefore read freed
memory (hif_dev->udev, the first field of struct hif_device_usb):

The fw_done barrier only makes disconnect wait for the firmware chain to
*terminate*; it does not protect the outer ath9k_hif_request_firmware()
frame that re-armed the request and keeps touching hif_dev afterwards.
Drop the post-request dev_info(): it is the only use of hif_dev after the
async request is armed, and it is purely informational (the dev_err() on the
failure path runs only when request_firmware_nowait() did not arm a callback,
so hif_dev is still alive there).
This was first reported by syzbot as a single, non-reproduced crash that was
later auto-obsoleted, and was independently rediscovered by the reFuzz fuzzer,
which produced a C reproducer (USB-gadget connect/disconnect of an ath9k_htc
device whose firmware download fails). The vulnerable code is unchanged and
still present in v7.1-rc6, where the slab-use-after-free reproduces under KASAN
once the (sub-microsecond) race window is widened.

remove_waiter() dereferences the NULL pointer in waiter->task.
That is already handled by Davidlohr in commit 40a25d59e85b3

The batadv_skb_set_priority() receives an SKB with the inner ethernet
header at position "offset". When it tries to extract the IPv4 and IPv6
header, it needs to skip the ethernet header to get access to the IP
header.
But for VLAN header, it performs the access with the struct vlan_ethhdr.
This struct contains both both the ethernet header and the VLAN header. It
is therefore incorrect to skip over the whole vlan_ethhdr size to get
access to the vlan_ethhdr.

When vm_insert_pages() fails, the error path calls vma->vm_ops->close(vma)
which internally calls drm_gem_vm_close() → drm_gem_object_put(),
releasing the GEM object reference acquired at the start of the function.
However, the close_vma label then falls through to put_obj, which calls
drm_gem_object_put() a second time on the same object.
If the first put releases the last reference, the object is freed and the
second put accesses freed memory, causing a use-after-free.
Fix by returning directly from close_vma instead of falling through to
put_obj, since the close handler already performs all necessary cleanup
including the object put.
