CVE-2026-68221: Linux

Описание

Оригинално описание

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.
