Description

This security bulletin contains information about 1 vulnerability.


1) Memory leak (CVE-ID: CVE-2026-23453)

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:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local attacker to cause a denial of service.

The vulnerability exists due to a memory leak in emac_run_xdp() when processing dropped packets in non-zero-copy mode. A local attacker can trigger XDP_DROP in standard page pool mode to cause a denial of service.

This issue affects the icssg-prueth driver and can lead to out-of-memory conditions because pages are not returned to the page pool.
