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

usb: typec: ucsi: glink: fix use-after-free of ucsi on remove

The pmic_glink client is released by the devres cleanup, which runs
after pmic_glink_ucsi_remove() has returned, so its notification
callbacks can queue work until then. Work that runs after
ucsi_unregister() has been called touches freed state: it dereferences
the connector array that ucsi_unregister() freed, or registers and
unregisters the instance a second time.

Disable both work items with disable_work_sync() before unregistering,
and unregister only if the instance is still registered.

This issue was found by an in-house static analysis tool.
