CVE-2026-98594

A flaw was found in the Linux kernel's Broadcom Tigon3 (tg3) ethernet driver. When the driver encounters an error during device initialization, it fails to properly release and unregister associated networking hardware resources. A local user capable of triggering initialization failures could exploit this flaw, leading to unreleased kernel resources and a potential Denial of Service (DoS) due to system instability.

This vulnerability is rated as Low impact because exploitation requires access to systems equipped with Broadcom Tigon3 network adapters and the ability to trigger hardware probe initialization failures. The flaw results exclusively in unreleased kernel resources, causing a minor resource leak without enabling privilege escalation or information disclosure. Furthermore, triggering the condition under typical enterprise deployment requires privileged local access or simulated device hotplugging.
