CVE-2026-68203
In the Linux kernel, the following vulnerability has been resolved:
media: vivid: fix cleanup bugs in vivid_init()
When platform_device_register() fails in vivid_init(), the embedded struct device in vivid_pdev has already been initialized by device_initialize(), but the failure path jumps to free_output_strings without dropping the device reference for the current platform device:
This leads to a reference leak when platform_device_register() fails. Fix this by calling platform_device_put() before jumping to the common cleanup path.
Also, the unreg_driver label incorrectly calls platform_driver_register() instead of platform_driver_unregister(), which breaks cleanup when workqueue creation fails after successful driver registration. Fix that as well.

The reference leak was identified by a static analysis tool I developed and confirmed by manual review. The incorrect cleanup call was found during code inspection.
