| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-30 and 6.9.13-55, when ImageMagick is built without Cairo support, a crafted RSVG image that reaches a resource limit can cause the RSVG decoder to free image state twice and then use freed memory, crashing the process. This issue is fixed in versions 7.1.2-30 and 6.9.13-55. |

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: keep fallback association elements alive
Associating to a non-transmitted MBSSID profile reads freed memory while
determining the operating channel and applying HT capabilities.
When an association response omits WMM, HT, or VHT information,
ieee80211_assoc_config_link() parses the cached BSS IEs and copies the
missing element pointers out of that fallback parse. For a
non-transmitted MBSSID profile those pointers refer to merged-profile
storage owned by the parse object, and the fallback block frees that
object at its end. The copied pointers are used afterwards to determine
the operating channel, configure bandwidth, and apply HT capabilities.
Keep the fallback parse result alive until association setup finishes.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix mesh fast xmit path deletion UAF
mesh_fast_tx_cache() stores raw mesh_path pointers. Path deletion
flushes the cache and then frees the path with kfree_rcu(), but a
lookup that already holds the path can insert a new cache entry
after the flush. The cache then points at freed memory.
Set MESH_PATH_DELETED before flushing, and skip inserting a cache
entry if the path or MPP path is already deleted. Check this under
the cache walk lock so it is ordered with the flush. Use WRITE_ONCE()
for the deletion flag updates because the cache check reads flags
without taking state_lock. |

thunderbolt: Fix KASAN reported use-after-free when request is canceled
Alan reported that when doing stress testing sometimes KASAN notices
use-after-free during control channel operation (stripped down keeping
the relevant parts):

The last stack trace is helpful because it shows that we are cancelling
a request and looking at tb_cfg_request_cancel() what might happen is
that tb_cfg_request_work() completes right before tb_cfg_request_cancel()
starts and because of this it will call schedule_work() queueing the
same work to run again. However, it is already removed from the
request_queue and reference count is dropped so when
tb_cfg_request_work() triggers again it will access memory that is
already released.
Fix this so that we first make sure a cancelled request is not handed
away from tb_cfg_request_find() or scheduled to run. Then instead of
relying on the worker to clean up the request we will do it in
tb_cfg_request_cancel() after the work is canceled from running. Make
tb_cfg_request_dequeue() release the request only if it was actually
removed from the queue. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: ad_sigma_delta: fix use-after-free on unbind
ad_sd_buffer_postenable() allocates sigma_delta->samples_buf with
devm_krealloc() at runtime, so its devres entry sits after all
probe-time entries of the driver. devm resources are released in
reverse allocation order, which means unbind frees samples_buf before
iio_device_unregister() disables the buffers and detaches the trigger
pollfunc. The data ready IRQ is still enabled at that point, so
ad_sd_trigger_handler() can still run and memcpy() incoming samples
into the freed samples_buf.
Fix this by preallocating the buffer in
devm_ad_sd_setup_buffer_and_trigger(), before the triggered buffer and
the IRQ are set up, so it is freed only after iio_device_unregister()
has drained the trigger handler via free_irq(). Size it for the worst
case of all sequencer slots being active; ad_sd_validate_scan_mask()
already caps the number of active channels at num_slots.
This issue was found by an in-house static analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: gyro: adis16136: fix unprotected debugfs reads
The serial_number file operations are open coded and never call
debugfs_file_get(), which debugfs_create_file_unsafe() requires.
debugfs_remove_recursive() therefore does not wait for a read in
progress, and unbind frees the iio_dev underneath it.
Use debugfs_create_file() instead. |
| 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. |
