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.
