Overview

CVE-2026-98565 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: dsa: mt7530: fix NULL dereference on unbind of MT7531 and MT7621

The core and io supplies are only requested for ID_MT7530: both the

devm_regulator_get() in probe and the regulator_enable() in

mt7530_setup() are guarded by the switch id, but mt7530_remove()

disables them unconditionally. On an MT7621 or an MT7531 both pointers

are still NULL from devm_kzalloc(), so rmmod or a sysfs unbind calls

regulator_disable() on NULL.
