"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmedia: vivid: fix cleanup bugs in vivid_init()\n\nWhen platform_device_register() fails in vivid_init(), the embedded\nstruct device in vivid_pdev has already been initialized by\ndevice_initialize(), but the failure path jumps to free_output_strings\nwithout dropping the device reference for the current platform device:\n\n vivid_init()\n -> platform_device_register(&vivid_pdev)\n -> device_initialize(&vivid_pdev.dev)\n -> setup_pdev_dma_masks(&vivid_pdev)\n -> platform_device_add(&vivid_pdev)\n\nThis leads to a reference leak when platform_device_register() fails.\nFix this by calling platform_device_put() before jumping to the common\ncleanup path.\n\nAlso, the unreg_driver label incorrectly calls\nplatform_driver_register() instead of platform_driver_unregister(),\nwhich breaks cleanup when workqueue creation fails after successful\ndriver registration. Fix that as well.\n\nThe reference leak was identified by a static analysis tool I developed\nand confirmed by manual review. The incorrect cleanup call was found\nduring code inspection."
