Overview

CVE-2026-23389 is a medium-severity vulnerability. It was published on March 25, 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:

ice: Fix memory leak in ice_set_ringparam()

In ice_set_ringparam, tx_rings and xdp_rings are allocated before

rx_rings. If the allocation of rx_rings fails, the code jumps to

the done label leaking both tx_rings and xdp_rings. Furthermore, if

the setup of an individual Rx ring fails during the loop, the code jumps

to the free_tx label which releases tx_rings but leaks xdp_rings.

Fix this by introducing a free_xdp label and updating the error paths to

ensure both xdp_rings and tx_rings are properly freed if rx_rings

allocation or setup fails.

Compile tested only. Issue found using a prototype static analysis tool

and code review.

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.
