Overview

CVE-2026-89883 is a high-severity vulnerability. It was published on September 16, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

media: rc: sunxi-cir: Unregister rc device on probe failure

After rc_register_device() succeeds, later probe failures must undo the

registration with rc_unregister_device(). The current error path jumps to

the allocation cleanup label and only calls rc_free_device(), leaving the

rc device registration and resources created by rc_register_device()

behind.

Add a registered-device unwind label for the IRQ lookup, IRQ request, and

hardware initialization failure paths. Keep rc_free_device() for failures

before rc_register_device() succeeds.

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.
