Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
media: v4l2-subdev: Fix alloc failure check in v4l2_subdev_call_state_try()<br />
<br />
v4l2_subdev_call_state_try() macro allocates a subdev state with<br />
__v4l2_subdev_state_alloc(), but does not check the returned value. If<br />
__v4l2_subdev_state_alloc fails, it returns an ERR_PTR, and that would<br />
cause v4l2_subdev_call_state_try() to crash.<br />
<br />
Add proper error handling to v4l2_subdev_call_state_try().
