CVE-2026-68203

/// Technical description

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:

vivid_init()

-> platform_device_register(&vivid_pdev)

-> device_initialize(&vivid_pdev.dev)

-> setup_pdev_dma_masks(&vivid_pdev)

-> platform_device_add(&vivid_pdev)

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.
