In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
usb: typec: hd3ss3220: track VBUS enable state per consumer<\/p>\n
regulator_is_enabled() reports the aggregate regulator state, not
\nwhether this consumer holds an enable reference. If another consumer
\nenables VBUS first, the driver can skip its own regulator_enable() call
\nand later attempt to drop a reference it never acquired, triggering an
\nunbalanced regulator disable warning.<\/p>\n
Track successful enable and disable calls locally. Keep the state
\nunchanged when an operation fails so a later role or ID notification
\nretries the operation while this consumer keeps balanced references.<\/p>\n","protected":false},"excerpt":{"rendered":"
