Description OSIDB Bzimport 2024-10-22 08:01:06 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: pci: cx23885: check cx23885_vdev_init() return

cx23885_vdev_init() can return a NULL pointer, but that pointer
is used in the next line without a check.

Add a NULL pointer check and go to the error unwind if it is NULL.
