Summary
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.
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.
