Overview

CVE-2026-22982 is a medium-severity vulnerability. It was published on January 23, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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:

net: mscc: ocelot: Fix crash when adding interface under a lag

Commit 15faa1f67ab4 ("lan966x: Fix crash when adding interface under a lag")

fixed a similar issue in the lan966x driver caused by a NULL pointer dereference.

The ocelot_set_aggr_pgids() function in the ocelot driver has similar logic

and is susceptible to the same crash.

This issue specifically affects the ocelot_vsc7514.c frontend, which leaves

unused ports as NULL pointers. The felix_vsc9959.c frontend is unaffected as

it uses the DSA framework which registers all ports.

Fix this by checking if the port pointer is valid before accessing it.

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.
