CVE-2026-89737

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

usb: typec: thunderbolt: Disable work before freeing tbt on remove

tbt_altmode_remove() drops the plug and cable references without
draining tbt->work. The work function dereferences those references,
and can also requeue itself in its error path. The VDM callbacks can
queue the same work item.

Disable and drain tbt->work before dropping the references. This waits
for an existing invocation and prevents subsequent schedule_work()
calls from queueing it during teardown.

This issue was found by an in-house static analysis tool and confirmed
by manual code review.
