CVE-2026-89737: Linux

Описание

Оригинално описание

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.
