CVE-2026-68221

Technical Description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
