CVE-2022-50711

Memory leak via omitted WED cleanup

Published Dec 24, 2025 · Updated Dec 24, 2025

A resource leak in the MediaTek Ethernet driver in Linux 5.19 through 6.0.5 allows attackers to consume kernel memory via unspecified vectors. The mtk_probe function calls mtk_wed_add_hw but omits the matching mtk_wed_exit call on probe-error and module-removal paths, leaving the WED allocation unreleased. The flaw requires WED hardware initialization followed by probe failure or module removal; public records do not establish attacker control or service interruption.
