Overview

CVE-2026-98620 is a known-severity vulnerability. It was published on October 18, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

net: ethernet: mtk_eth_soc: unregister net_devices in case of probe failure

If register_netdev() fails for one of the MTK_MAX_DEVS devices in

mtk_probe(), the error path jumps to err_deinit_ppe, skipping

mtk_unreg_dev(). The previously registered net_devices are then freed by

mtk_free_dev() while still in NETREG_REGISTERED state, hitting the

BUG_ON(dev->reg_state != NETREG_UNREGISTERED).

Route the register_netdev() failure to err_unreg_netdev so the net_devices

registered so far are properly unregistered before being freed.
