thunderbolt: Fix NULL dereference in tb_remove_work()
There is a slight race between tb_remove_work() and tb_domain_remove()
which leads to dereferencing a NULL tb->root_switch pointer inside
tb_free_unplugged_xdomains():
Thread A Thread B
tb_remove_work()
tb_domain_remove()
mutex_lock(&tb->lock)
tb_stop()
/* doesn't cancel a running callback */
cancel_delayed_work(&tcm->remove_work)
...
tb_switch_remove(tb->root_switch)
tb->root_switch = NULL
mutex_unlock(&tb->lock)
mutex_lock(&tb->lock)
...
/* without checking ->root_switch */
tb_free_unplugged_xdomains(tb->root_switch)
mutex_unlock(&tb->lock)
Commit a8937f35cf39 ("thunderbolt: Remove XDomain from the bus without
holding tb->lock") doesn't seem right to move tb_free_unplugged_xdomains()
out of the &tb->lock section and the check for tb->root_switch, in
particular. It states:
For this reason separate removing the XDomain from the topology data
structures (where we need the lock) from unregistering the device from
the bus (where remove callbacks of the drivers are being called).
tb_free_unplugged_xdomains() belongs to the former group of functions
requiring the lock. And it also calls tb_xdomain_remove() which should
only be called with &tb->lock held.
Found by Linux Verification Center (linuxtesting.org) with Svace static
analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: Reject oversized XDomain properties responses
tb_xdp_properties_request() allocates room for 45 data dwords in its
252-byte response buffer. The XDomain length field is six bits wide,
however, and a malicious peer can set it to 63. After the fixed response
fields are subtracted, the driver treats this as 48 data dwords.
Commit 322e93448d90 ("thunderbolt: Clamp XDomain response data copy to
allocation size") only bounds the copy against data_len. If data_len is
at least 48, memcpy() reads 192 bytes from the 180-byte res->data array,
causing a 12-byte heap out-of-bounds read. Commit 4db2bd2ed478
("thunderbolt: Limit XDomain response copy to actual frame size") limits
the earlier copy but does not constrain this header-derived length.
Reject response data lengths that exceed the allocated source buffer
before copying them into the assembled property block. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: discard post-EOF pagecache when extending a file via clone range
cifs_remap_file_range() discarded the pagecache only for the folios
overlapping the destination region, so when a clone extends the file the
folio straddling the old EOF - which may hold data dirtied past EOF
through an mmap - was never dropped and became visible as file content
once the file was extended.
Start the discard at the smaller of fstart and the old EOF. i_size is
still old here, so nothing past the old EOF is flushed to the server. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: accel: kxcjk-1013: reject duplicate event disable
The IIO core does not filter duplicate writes to the event enable
attribute. kxcjk1013_write_event_config() already ignores repeated
enable requests, but a repeated disable request still calls
kxcjk1013_set_power_state(data, false), dropping a runtime PM reference
that was not acquired for this request. This can underflow the runtime
PM usage count and trigger a "Runtime PM usage count underflow" warning.
Return early when the requested state already matches ev_enable_state. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ad4030: fix invalid oversampling_ratio validation
In ad4030_set_avg_frame_len(), the logarithm is calculated before input
validation. Passing zero or negative values leads to an undefined result
from ilog2().
Validate that the input is strictly positive prior to computing its
logarithm. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ade9000: fix NULL pointer dereference in clkout registration
ade9000_setup_clkout() passes NULL as the register address when
registering a divider clock. During clock registration, the common
clock framework calls clk_divider_recalc_rate(), which dereferences
the address through readl(). As a result, probing an ADE9000 configured
as a clock provider with an external input clock crashes.
CLKOUT passes CLKIN through without changing its rate. Register it as
a 1:1 fixed-factor clock, which does not require register access.
This change does not affect the configuration using the internal clock,
for which the driver does not register a clock provider. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ade9000: handle Phase C dip events in IRQ1 handler
ADE9000_ST1_CROSSING_DEPTH is the exclusive upper bound for scanning the
STATUS1 event bits, so a value of 25 left out the highest event bit,
ADE9000_ST1_DIPC_BIT (bit 25). Phase C dip events were never reported.
Bump the value to 26 so bit 25 is scanned. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: pac1934: check ACPI label duplication
A label duplication failure currently reaches the terminating-byte
write. Release the ACPI result and abort before accessing the missing
label; earlier labels are managed by devres.
Detected by static analysis and reviewed with AI-assisted source auditing. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: stm32-adc: fix possible division by zero in processed channel
In case the conversion has failed or returned zero, processing *val
can lead to a division by zero. Need to check for errors, or converted
value is zero, before processing the data. In case the converted value
is zero, e.g. the Vrefint channel, this should be considered as invalid
in all cases. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: sun4i-gpadc-iio: clean up on thermal zone registration failure
If devm_thermal_of_zone_register() fails, probe returns without
unregistering the IIO map array or disabling runtime PM.
Jump to err_map to release them. |
| The ACF Frontend Admin by DynamiApps WordPress plugin through 3.29.13 does not perform a capability check on one of its form-submission actions before writing submitted values into the site's global ACF options store, allowing unauthenticated visitors to overwrite site-wide option values via a public form. |
| In the Linux kernel, the following vulnerability has been resolved:
sysctl: Check range in proc_dointvec_ms_jiffies_minmax
Add the range check to do_proc_int_conv_ms_jiffies_minmax that commit
d174174c6776 ("sysctl: replace SYSCTL_INT_CONV_CUSTOM macro with
functions") incorrectly removed. |
| Enterprise Architect is vulnerable to XML External Entity (XXE) injection in the XSLT Debugger feature. When a user loads a crafted XML file containing a `DOCTYPE` with an external DTD reference, the parser processes external entities, allowing an attacker to read arbitrary files from the victim's filesystem.
Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 17.1 but may also affect other versions. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: buffer: serialize buffer teardown with mode claims
Buffer-mode claims hold mlock to guarantee that the device remains in
buffer mode until the claim is released. Normal buffer updates take
info_exist_lock followed by mlock in iio_update_buffers().
However, iio_device_unregister() disables and deactivates all buffers
without taking mlock. This can invalidate buffer state, including
active_scan_mask, while a buffer-mode claim is held.
Take mlock in iio_disable_all_buffers() so that unregister honors the
mode-claim lifetime guarantee. The info_exist_lock -> mlock ordering
matches iio_update_buffers(). |
| In the Linux kernel, the following vulnerability has been resolved:
iio: buffer: Ensure bounce buffer used for unaligned case is zeroed.
iio_push_to_buffers_with_ts_unaligned() leaks uninitialized heap memory
to userspace if the data passed in is not a multiple of 8 bytes and the
timestamp is enabled. Specify __GFP_ZERO for the devm_krealloc()
to ensure any extra space is cleared. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: health: max30102: fix NULL dereference in interrupt handler
The interrupt is requested in max30102_probe() and stays enabled
for the lifetime of the device, but indio_dev->active_scan_mask is only
valid while a buffer is enabled. When an interrupt arrives while no
buffer is enabled, the handler dereferences the NULL active_scan_mask:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000
Call trace:
__bitmap_weight+0x64/0x98 (P)
max30102_interrupt_handler+0x48/0x160 [max30102]
Call max30102_fifo_count() at the top of the handler and return early
unless it reports a FIFO sample is ready. Because FIFO_RDY is the only
interrupt source enabled in max30102_chip_init(), an invocation of
max30102_interrupt_handler() without the FIFO_RDY interrupt status bit
set carries no data to read and can return before touching
active_scan_mask. A negative return from max30102_fifo_count()
indicates a failed interrupt status read and is treated the same way. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: imu: adis16400: fix unprotected debugfs reads
adis16400_serial_number_fops is open coded and never calls
debugfs_file_get(), so debugfs_remove_recursive() does not wait for a
read in progress and unbind frees the iio_dev underneath it.
Commit ae1d37a9bb4b ("iio: imu: adis16400: use DEFINE_DEBUGFS_ATTRIBUTE
instead of DEFINE_SIMPLE_ATTRIBUTE") converted product_id and
flash_count to DEFINE_DEBUGFS_ATTRIBUTE, which protects itself, but
moved all three files to debugfs_create_file_unsafe().
serial_number prints three registers as "%.4x-%.4x-%.4x" and
DEFINE_DEBUGFS_ATTRIBUTE() formats a single u64, so it cannot be
converted without changing what the file returns. adis16475 and
adis16550 already use debugfs_create_file() for their open coded
files. Use it here too. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: light: gp2ap020a00f: drain irq_work after free_irq
The threaded IRQ handler queues data->work through irq_work_queue() so
the trigger is polled from a per-CPU context. free_irq() does not flush
an irq_work the handler already queued, so after gp2ap020a00f_remove()
returns that work may still run and call iio_trigger_poll() on data->trig,
which the devm cleanup has already freed, causing a use-after-free.
Add irq_work_sync(&data->work) after free_irq() in remove() and in the
probe error path, mirroring commit 78601726d4a5 ("iio: trigger: sysfs:
fix use-after-free on remove").
Found by an in-house static analysis tool, confirmed by manual review. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: light: rohm-bu27034: Fix infinite delay on error
When reading an integration-time fails, the code will use error code to
compute the sleep time.
Fix this by using the smallest integration time as a default if
reading fails. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: proximity: pulsedlight: fix iio_device left registered on PM setup failure
pm_runtime_set_active() failing in probe() jumps to error_unreg_buffer,
which only calls iio_triggered_buffer_cleanup() -- it does not undo the
iio_device_register() that already succeeded a few lines above. probe()
then returns the error, the devm-managed indio_dev is freed, but the
iio core still has it registered: the sysfs/chardev nodes stay live and
point at freed memory.
Add an error_unreg_dev label that unregisters the iio device before
falling through to the existing buffer cleanup, mirroring the teardown
order already used in lidar_remove(). |
