CVE-2026-68221 Vulnerability Summary

CVE-2026-68221: 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.

Assessing the Risk of CVE-2026-68221

Access Complexity Graph

The exploitability of CVE-2026-68221 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2026-68221

No exploitability data is available for CVE-2026-68221.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
