CVE-2023-33203: Race Condition
First published: Tue May 02 2023(Updated: )
In emac_probe, &adpt->work_thread is bound with emac_work_thread. Then it will be started by timeout handler emac_tx_timeout or a IRQ handler emac_isr. If we remove the driver which will call emac_remove to make cleanup, there may be a unfinished work. This could lead to a use-after-free.
