CVE-2026-90028— usb: typec: hd3ss3220: track VBUS enable state per consumer

Quick assessment

Affected
Linux Linux
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，已解决以下漏洞： USB：typec：hd3ss3220：按消费者跟踪 VBUS 使能状态 报告的是调节器的整体状态，而非当前消费者是否持有使能引用。如果其他消费者先使能了 VBUS，驱动可能会跳过自身的 调用，之后又尝试释放一个它从未获取的引用，从而触发不平衡的调节器禁用警告。 本地跟踪成功的使能和禁用操作。当操作失败时保持状态不变，以便后续的角色或 ID 通知可以重试该操作，同时确保当前消费者维持引用平衡。

Vulnerability Title
usb: typec: hd3ss3220: track VBUS enable state per consumer
Source: CVE Program / CVE List V5
Vulnerability Description
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.
