Overview

CVE-2026-23180 is a high-severity vulnerability. It was published on February 14, 2026 and has a CVSS 3.1 base score of 7.0 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.0, 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:

dpaa2-switch: add bounds check for if_id in IRQ handler

The IRQ handler extracts if_id from the upper 16 bits of the hardware

status register and uses it to index into ethsw->ports[] without

validation. Since if_id can be any 16-bit value (0-65535) but the ports

array is only allocated with sw_attr.num_ifs elements, this can lead to

an out-of-bounds read potentially.

Add a bounds check before accessing the array, consistent with the

existing validation in dpaa2_switch_rx().

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.

How can CyberStrike help with CVE-2026-23180?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-23180 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
