CVE-2026-52907

Linux · Kernel

An off-by-one error in the Linux kernel's Rockchip camera interface driver allows for out-of-bounds memory access.

Executive summary

An off-by-one vulnerability in the Linux kernel Rockchip driver poses a significant risk of memory corruption or system instability.

Vulnerability

This is an out-of-bounds memory access vulnerability within the rkcif driver, caused by incorrect array boundary comparisons. The issue requires local access to the affected hardware/driver context, typically by an authenticated user or process.

Business impact

The vulnerability carries a CVSS score of 7.8, indicating a high severity. Successful exploitation could lead to local privilege escalation or kernel-level memory corruption, resulting in system crashes or the potential for unauthorized code execution, directly impacting system availability and integrity.

Remediation

Immediate Action: Apply the latest security patches provided by your Linux distribution maintainer to address the rkcif off-by-one bug.

Proactive Monitoring: Monitor system logs for kernel panic events or unexpected segmentation faults that may indicate attempts to trigger memory corruption.

Compensating Controls: Restrict access to the camera interface or associated device nodes to only necessary system users to minimize the attack surface.

Exploitation status

Public Exploit Available: false

Analyst recommendation

Given the potential for kernel-level impact, administrators should prioritize updating the Linux kernel to the patched version as soon as it becomes available in their distribution’s repository. Testing in a staging environment is advised to ensure compatibility before deploying to production systems.
