In the Linux kernel, the following vulnerability has been resolved:
dmaengine: fix NULL pointer in channel unregistration function
__dma_async_device_channel_register() can fail. In case of failure,
chan->local is freed (with free_percpu()), and chan->local is nullified.
When dma_async_device_unregister() is called (because of managed API or
intentionally by DMA controller driver), channels are unconditionally
unregistered, leading to this NULL pointer:
[ 1.318693] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000d0
[...]
[ 1.484499] Call trace:
[ 1.486930] device_del+0x40/0x394
[ 1.490314] device_unregister+0x20/0x7c
[ 1.494220] __dma_async_device_channel_unregister+0x68/0xc0
Look at dma_async_device_register() function error path, channel device
unregistration is done only if chan->local is not NULL.
Then add the same condition at the beginning of
__dma_async_device_channel_unregister() function, to avoid NULL pointer
issue whatever the API used to reach this function.

In the Linux kernel, the following vulnerability has been resolved:
bus: mhi: host: Drop chan lock before queuing buffers
Ensure read and write locks for the channel are not taken in succession by
dropping the read lock from parse_xfer_event() such that a callback given
to client can potentially queue buffers and acquire the write lock in that
process. Any queueing of buffers should be done without channel read lock
acquired as it can result in multiple locks and a soft lockup.

In Santesoft Sante FFT Imaging versions 1.4.1 and prior once a user opens a malicious DCM file on affected FFT Imaging installations, a local attacker could perform an out-of-bounds write, which could allow for arbitrary code execution.

In access_secure_service_from_temp_bond of btm_sec.cc, there is a possible way to achieve keystroke injection due to improper input validation. This could lead to remote (proximal/adjacent) escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
