Technical description

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

Revert "usb: typec: ucsi: add a common function ucsi_unregister_connectors()"

The recent commit 87d0e2f41b8c ("usb: typec: ucsi: add a common

function ucsi_unregister_connectors()") introduced a regression that

caused NULL dereference at reading the power supply sysfs. It's a

stale sysfs entry that should have been removed but remains with NULL

ops. The commit changed the error handling to skip the entries after

a NULL con->wq, and this leaves the power device unreleased.

For addressing the regression, the straight revert is applied here.

Further code improvements can be done from the scratch again.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
