Description

A flaw was found in the Linux kernel's USB Type-C Port Manager (TCPM). This issue may result in a denial of service (DoS) or unintended power delivery on the affected port. When a USB Type-C cable is disconnected while signaling a Fast Role Swap (FRS), the controller autonomously begins sourcing bus voltage (VBUS) power, but the role-swap sequence fails because the connection is broken. Due to improper state handling, the driver fails to trigger error recovery or reset the port, leaving power delivery active on the disconnected interface.
