CVE-2026-90028

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

usb: typec: hd3ss3220: track VBUS enable state per consumer

regulator_is_enabled() reports the aggregate regulator state, not
whether this consumer holds an enable reference. If another consumer
enables VBUS first, the driver can skip its own regulator_enable() call
and later attempt to drop a reference it never acquired, triggering an
unbalanced regulator disable warning.

Track successful enable and disable calls locally. Keep the state
unchanged when an operation fails so a later role or ID notification
retries the operation while this consumer keeps balanced references.
