01 May 2024 — In the Linux kernel, the following vulnerability has been resolved: wifi: rtl8xxxu: add cancel_work_sync() for c2hcmd_work The workqueue might still be running, when the driver is stopped. To avoid a use-after-free, call cancel_work_sync() in rtl8xxxu_stop(). En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: wifi: rtl8xxxu: agregue cancel_work_sync() para c2hcmd_work Es posible que la cola de trabajo aún esté ejecutándose cuando se detiene el controlador.
