Overview

CVE-2026-43102 is a medium-severity vulnerability. It was published on May 6, 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: airoha: Fix memory leak in airoha_qdma_rx_process()

If an error occurs on the subsequents buffers belonging to the

non-linear part of the skb (e.g. due to an error in the payload length

reported by the NIC or if we consumed all the available fragments for

the skb), the page_pool fragment will not be linked to the skb so it will

not return to the pool in the airoha_qdma_rx_process() error path. Fix the

memory leak partially reverting commit 'd6d2b0e1538d ("net: airoha: Fix

page recycling in airoha_qdma_rx_process()")' and always running

page_pool_put_full_page routine in the airoha_qdma_rx_process() error

path.

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.
