Description

This security bulletin contains information about 1 vulnerability.


1) Missing release of memory after effective lifetime (CVE-ID: CVE-2026-23258)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to cause a memory leak.

The vulnerability exists due to improper memory management in the net: liquidio component when initializing network devices. A local user can trigger a failure during queue setup to cause a memory leak.

The issue occurs because the netdev pointer is not initialized before calling netif_set_real_num_rx_queues() and netif_set_real_num_tx_queues(), leading to failure in freeing the allocated netdev on error paths.
