  3. CVE-2023-52509
In the Linux kernel, the following vulnerability has been resolved: ravb: Fix use-after-free issue in ravb_tx_timeout_work() The ravb_stop() should call cancel_work_sync(). Otherwise, ravb_tx_timeout_work() is possible to use the freed priv after ravb_remove() was called like below: CPU0 CPU1 ravb_tx_timeout() ravb_remove() unregister_netdev() free_netdev(ndev) // free priv ravb_tx_timeout_work() // use priv unregister_netdev() will call .ndo_stop() so that ravb_stop() is called. And, after phy_stop() is called, netif_carrier_off() is also called. So that .ndo_tx_timeout() will not be called after phy_stop().

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ravb: soluciona el problema de Use After Free en ravb_tx_timeout_work(). Ravb_stop() debería llamar a cancel_work_sync(). De lo contrario, ravb_tx_timeout_work() es posible usar el privilegio liberado después de que se llamó a ravb_remove() como se muestra a continuación: CPU0 CPU1 ravb_tx_timeout() ravb_remove() unregister_netdev() free_netdev(ndev) // priv libre ravb_tx_timeout_work() // usa priv unregister_netdev() llamará a .ndo_stop() para que se llame a ravb_stop(). Y, después de llamar a phy_stop(), también se llama a netif_carrier_off(). De modo que .ndo_tx_timeout() no será llamado después de phy_stop().
