    Changed Description In the Linux kernel, the following vulnerability has been resolved: hamradio: defer ax25 kfree after unregister_netdev There is a possible race condition (use-after-free) like below (USE) | (FREE) ax25_sendmsg | ax25_queue_xmit | dev_queue_xmit | __dev_queue_xmit | __dev_xmit_skb | sch_direct_xmit | ... xmit_one | netdev_start_xmit | tty_ldisc_kill __netdev_start_xmit | mkiss_close ax_xmit | kfree ax_encaps | | Even though there are two synchronization primitives before the kfree: 1. wait_for_completion(&ax->dead). This can prevent the race with routines from mkiss_ioctl. However, it cannot stop the routine coming from upper layer, i.e., the ax25_sendmsg. 2. netif_stop_queue(ax->dev). It seems that this line of code aims to halt the transmit queue but it fails to stop the routine that already being xmit. This patch reorder the kfree after the unregister_netdev to avoid the possible UAF as the unregister_netdev() is well synchronized and won't return if there is a running routine. Rejected reason: This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.

    Removed Translation Title: kernel de Linux Description: En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: hamradio: diferir ax25 kfree después de unregister_netdev Existe una posible condición de ejecución (use-after-free) como la siguiente (USE) | (GRATIS) ax25_sendmsg | ax25_queue_xmit | dev_queue_xmit | __dev_queue_xmit | __dev_xmit_skb | sch_direct_xmit | ... xmit_one | netdev_start_xmit | tty_ldisc_kill __netdev_start_xmit | mkiss_close ax_xmit | kfree ax_encaps | | Aunque hay dos primitivas de sincronización antes de kfree: 1. wait_for_completion(&ax->dead). Esto puede evitar la ejecución con rutinas de mkiss_ioctl. Sin embargo, no puede detener la rutina que proviene de la capa superior, es decir, ax25_sendmsg. 2. netif_stop_queue(ax->dev). Parece que esta línea de código tiene como objetivo detener la cola de transmisión pero no logra detener la rutina que ya se está transmitiendo. Este parche reordena kfree después de unregister_netdev para evitar el posible UAF ya que unregister_netdev() está bien sincronizado y no regresará si hay una rutina en ejecución.
