Security Vulnerabilities
- CVEs Published In December 2024
In the Linux kernel, the following vulnerability has been resolved:
media: qcom: camss: fix error path on configuration of power domains
There is a chance to meet runtime issues during configuration of CAMSS
power domains, because on the error path dev_pm_domain_detach() is
unexpectedly called with NULL or error pointer.
One of the simplest ways to reproduce the problem is to probe CAMSS
driver before registration of CAMSS power domains, for instance if
a platform CAMCC driver is simply not built.

In the Linux kernel, the following vulnerability has been resolved:
btrfs: ref-verify: fix use-after-free after invalid ref action
At btrfs_ref_tree_mod() after we successfully inserted the new ref entry
(local variable 'ref') into the respective block entry's rbtree (local
variable 'be'), if we find an unexpected action of BTRFS_DROP_DELAYED_REF,
we error out and free the ref entry without removing it from the block
entry's rbtree. Then in the error path of btrfs_ref_tree_mod() we call
btrfs_free_ref_cache(), which iterates over all block entries and then
calls free_block_entry() for each one, and there we will trigger a
use-after-free when we are called against the block entry to which we
added the freed ref entry to its rbtree, since the rbtree still points
to the block entry, as we didn't remove it from the rbtree before freeing
it in the error path at btrfs_ref_tree_mod(). Fix this by removing the
new ref entry from the rbtree before freeing it.
Syzbot report this with the following stack traces:

In the Linux kernel, the following vulnerability has been resolved:
leds: class: Protect brightness_show() with led_cdev->led_access mutex
There is NULL pointer issue observed if from Process A where hid device
being added which results in adding a led_cdev addition and later a
another call to access of led_cdev attribute from Process B can result
in NULL pointer issue.
Use mutex led_cdev->led_access to protect access to led->cdev and its
attribute inside brightness_show() and max_brightness_show() and also
update the comment for mutex that it should be used to protect the led
class device fields.

...
The cause of the problem is that when using sysfs to dynamically register
an i2c device, there is no platform data, but the probe process of ts2020
needs to use platform data, resulting in a null pointer being accessed.
Solve this problem by adding checks to platform data.

The power suppliers are always requested to suspend asynchronously,
dev_pm_domain_detach() requires the caller to ensure proper
synchronization of this function with power management callbacks.
otherwise the detach may led to kernel panic, like below:

In the Linux kernel, the following vulnerability has been resolved:
media: mtk-jpeg: Fix null-ptr-deref during unload module
The workqueue should be destroyed in mtk_jpeg_core.c since commit
09aea13ecf6f ("media: mtk-jpeg: refactor some variables"), otherwise
the below calltrace can be easily triggered.

In the Linux kernel, the following vulnerability has been resolved:
media: imx-jpeg: Set video drvdata before register video device
The video drvdata should be set before the video device is registered,
otherwise video_drvdata() may return NULL in the open() file ops, and led
to oops.
