CVE-2026-64463: usb: typec: tcpci_rt1711h: unregister TCPCI port with devres

Published Jul 25, 2026
·
Updated

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

usb: typec: tcpcirt1711h: unregister TCPCI port with devres

rt1711hprobe() registers the TCPCI port before requesting the interrupt and enabling alert interrupts. If either of those later steps fails, the probe function returns without unregistering the TCPCI port. The explicit unregister currently only happens from the remove callback.

Register a devres action immediately after tcpciregisterport() succeeds, so tcpciunregisterport() runs on later probe failures and on driver detach. Drop the remove callback to avoid unregistering the same port twice.

This issue was identified during our ongoing static-analysis research while reviewing kernel code.
