| In the Linux kernel, the following vulnerability has been resolved:
iio: light: as73211: Ensure buffer holes are zeroed
Given that the buffer is copied to a kfifo that ultimately user space
can read, ensure we zero it. |
| In the Linux kernel, the following vulnerability has been resolved:
comedi: Make insn_rw_emulate_bits() do insn->n samples
The `insn_rw_emulate_bits()` function is used as a default handler for
`INSN_READ` instructions for subdevices that have a handler for
`INSN_BITS` but not for `INSN_READ`. Similarly, it is used as a default
handler for `INSN_WRITE` instructions for subdevices that have a handler
for `INSN_BITS` but not for `INSN_WRITE`. It works by emulating the
`INSN_READ` or `INSN_WRITE` instruction handling with a constructed
`INSN_BITS` instruction. However, `INSN_READ` and `INSN_WRITE`
instructions are supposed to be able read or write multiple samples,
indicated by the `insn->n` value, but `insn_rw_emulate_bits()` currently
only handles a single sample. For `INSN_READ`, the comedi core will
copy `insn->n` samples back to user-space. (That triggered KASAN
kernel-infoleak errors when `insn->n` was greater than 1, but that is
being fixed more generally elsewhere in the comedi core.)
Make `insn_rw_emulate_bits()` either handle `insn->n` samples, or return
an error, to conform to the general expectation for `INSN_READ` and
`INSN_WRITE` handlers. |

LoongArch: BPF: Fix jump offset calculation in tailcall
The extra pass of bpf_int_jit_compile() skips JIT context initialization
which essentially skips offset calculation leaving out_offset = -1, so
the jmp_offset in emit_bpf_tail_call is calculated by
"#define jmp_offset (out_offset - (cur_offset))"
is a negative number, which is wrong. The final generated assembly are
as follow.
54: bgeu $a2, $t1, -8 # 0x0000004c
58: addi.d $a6, $s5, -1
5c: bltz $a6, -16 # 0x0000004c
60: alsl.d $t2, $a2, $a1, 0x3
64: ld.d $t2, $t2, 264
68: beq $t2, $zero, -28 # 0x0000004c
Before apply this patch, the follow test case will reveal soft lock issues.

| In the Linux kernel, the following vulnerability has been resolved:
jfs: Regular file corruption check
The reproducer builds a corrupted file on disk with a negative i_size value.
Add a check when opening this file to avoid subsequent operation failures. |
| An information leakage was addressed with additional validation. This issue is fixed in iOS 18.7.9 and iPadOS 18.7.9, iOS 26.4 and iPadOS 26.4, macOS Tahoe 26.4, tvOS 26.4, visionOS 26.4, watchOS 26.4. An app may be able to access sensitive user data. |
| This issue was addressed with improved checks. This issue is fixed in iOS 18.7.9 and iPadOS 18.7.9, iOS 26.4 and iPadOS 26.4, macOS Tahoe 26.4, tvOS 26.4, visionOS 26.4, watchOS 26.4. An app may be able to enumerate a user's installed apps. |
| In the Linux kernel, the following vulnerability has been resolved:
soc: qcom: pd-mapper: Fix element length in servreg_loc_pfr_req_ei
It looks element length declared in servreg_loc_pfr_req_ei for reason
not matching servreg_loc_pfr_req's reason field due which we could
observe decoding error on PD crash.
qmi_decode_string_elem: String len 81 >= Max Len 65
Fix this by matching with servreg_loc_pfr_req's reason field. |
| In the Linux kernel, the following vulnerability has been resolved:
media: v4l2-async: Fix error handling on steps after finding a match
Once an async connection is found to be matching with an fwnode, a
sub-device may be registered (in case it wasn't already), its bound
operation is called, ancillary links are created, the async connection
is added to the sub-device's list of connections and removed from the
global waiting connection list. Further on, the sub-device's possible own
notifier is searched for possible additional matches.
Fix these specific issues:
- If v4l2_async_match_notify() failed before the sub-notifier handling,
the async connection was unbound and its entry removed from the
sub-device's async connection list. The latter part was also done in
v4l2_async_match_notify().
- The async connection's sd field was only set after creating ancillary
links in v4l2_async_match_notify(). It was however dereferenced in
v4l2_async_unbind_subdev_one(), which was called on error path of
v4l2_async_match_notify() failure. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: amlogic: spifc-a4: unregister ECC engine on probe failure and remove() callback
aml_sfc_probe() registers the on-host NAND ECC engine, but teardown was
missing from both probe unwind and remove-time cleanup. Add a devm cleanup
action after successful registration so
nand_ecc_unregister_on_host_hw_engine() runs automatically on probe
failures and during device removal. |
| In the Linux kernel, the following vulnerability has been resolved:
ceph: do not propagate page array emplacement errors as batch errors
When fscrypt is enabled, move_dirty_folio_in_page_array() may fail
because it needs to allocate bounce buffers to store the encrypted
versions of each folio. Each folio beyond the first allocates its bounce
buffer with GFP_NOWAIT. Failures are common (and expected) under this
allocation mode; they should flush (not abort) the batch.
However, ceph_process_folio_batch() uses the same `rc` variable for its
own return code and for capturing the return codes of its routine calls;
failing to reset `rc` back to 0 results in the error being propagated
out to the main writeback loop, which cannot actually tolerate any
errors here: once `ceph_wbc.pages` is allocated, it must be passed to
ceph_submit_write() to be freed. If it survives until the next iteration
(e.g. due to the goto being followed), ceph_allocate_page_array()'s
BUG_ON() will oops the worker.
Note that this failure mode is currently masked due to another bug
(addressed next in this series) that prevents multiple encrypted folios
from being selected for the same write.
For now, just reset `rc` when redirtying the folio to prevent errors in
move_dirty_folio_in_page_array() from propagating. Note that
move_dirty_folio_in_page_array() is careful never to return errors on
the first folio, so there is no need to check for that. After this
change, ceph_process_folio_batch() no longer returns errors; its only
remaining failure indicator is `locked_pages == 0`, which the caller
already handles correctly. |
| In the Linux kernel, the following vulnerability has been resolved:
dm mpath: Add missing dm_put_device when failing to get scsi dh name
When commit fd81bc5cca8f ("scsi: device_handler: Return error pointer in
scsi_dh_attached_handler_name()") added code to fail parsing the path if
scsi_dh_attached_handler_name() failed with -ENOMEM, it didn't clean up
the reference to the path device that had just been taken. Fix this, and
steamline the error paths of parse_path() a little. |
| An authorization issue was addressed with improved state management. This issue is fixed in iOS 18.7.9 and iPadOS 18.7.9, iOS 26.4 and iPadOS 26.4, macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4, visionOS 26.4, watchOS 26.4. An app may be able to access sensitive user data. |
| A logic issue was addressed with improved restrictions. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. A malicious app may be able to break out of its sandbox. |
| In Modem IMS, there is a possible improper input validation. This could lead to remote denial of service with no additional execution privileges needed. |
| In the Linux kernel, the following vulnerability has been resolved:
rnbd-srv: Zero the rsp buffer before using it
Before using the data buffer to send back the response message, zero it
completely. This prevents any stray bytes to be picked up by the client
side when there the message is exchanged between different protocol
versions. |
| In the Linux kernel, the following vulnerability has been resolved:
gpio: sysfs: fix chip removal with GPIOs exported over sysfs
Currently if we export a GPIO over sysfs and unbind the parent GPIO
controller, the exported attribute will remain under /sys/class/gpio
because once we remove the parent device, we can no longer associate the
descriptor with it in gpiod_unexport() and never drop the final
reference.
Rework the teardown code: provide an unlocked variant of
gpiod_unexport() and remove all exported GPIOs with the sysfs_lock taken
before unregistering the parent device itself. This is done to prevent
any new exports happening before we unregister the device completely. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/ioc32: stop speculation on the drm_compat_ioctl path
The drm compat ioctl path takes a user controlled pointer, and then
dereferences it into a table of function pointers, the signature method
of spectre problems. Fix this up by calling array_index_nospec() on the
index to the function pointer list. |
| In Modem IMS, there is a possible improper input validation. This could lead to remote denial of service with no additional execution privileges needed. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: libertas: fix WARNING in usb_tx_block
The function usb_tx_block() submits cardp->tx_urb without ensuring that
any previous transmission on this URB has completed. If a second call
occurs while the URB is still active (e.g. during rapid firmware loading),
usb_submit_urb() detects the active state and triggers a warning:
'URB submitted while active'.
Fix this by enforcing serialization: call usb_kill_urb() before
submitting the new request. This ensures the URB is idle and safe to reuse. |
