In the Linux kernel, the following vulnerability has been resolved:
media: nuvoton: npcm-video: fix memory leaks in probe and remove
npcm_video_probe() allocates the npcm_video structure with kzalloc_obj()
but never frees it on any probe error path or in npcm_video_remove(),
leaking the allocation on every failed probe and every normal unbind.
Additionally, when npcm_video_setup_video() fails, the reserved memory
association established by of_reserved_mem_device_init() in
npcm_video_init() is not released, leaking the rmem_assigned_device
entry on the global list.
Fix both by adding kfree(video) to all probe error paths and to
npcm_video_remove(), and adding the missing
of_reserved_mem_device_release() call when npcm_video_setup_video()
fails.
