UBUNTU-CVE-2026-93225: High severity ubuntu/linux-hwe-edge vulnerability

Q: Which systems are exposed to this issue?

The affected Ubuntu kernel packages listed are linux-riscv, linux-realtime, linux-hwe-edge, linux-azure, linux-gcp, linux-azure-fde, linux-gke, and linux-aws-5.0. The issue is in the fsl-imx8mq-usb PHY driver and concerns its Type-C switch handling during driver probe.

Q: When does the leak occur?

The leak occurs when driver probe fails after imx95_usb_phy_get_tca() has succeeded. The prior cleanup existed only in the driver removal path, which is not invoked after a failed probe.

Q: How is the issue fixed?

The fix registers cleanup with devm_add_action_or_reset(), causing the Type-C switch to be released both when probing fails and when the driver is removed. The explicit imx95_usb_phy_put_tca() cleanup is consequently no longer needed in the removal path.

Updated

In the Linux kernel, the following vulnerability has been resolved: phy: fsl-imx8mq-usb: fix typec switch leak on probe error path If probe fails after imx95usbphygettca() succeeds, the typec switch leaks because the only cleanup path was in .remove(), which never runs on probe failure. Use devmaddactionorreset() so the switch is cleaned up on both probe failure and driver removal. The imx95usbphyputtca() is no longer needed, it will be removed in .remove() too.
