"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: bcmgenet: stop Tx NAPI before disabling the queues\n\nbcmgenet_netif_stop() and the Wake-on-LAN branch of bcmgenet_suspend()\nboth disable the Tx queues first and stop Tx NAPI several steps later. A\ncompletion in flight calls netif_tx_wake_queue() in between, and nothing\nstops the queue again, so a transmit can reach the rings after they have\nbeen freed.\n\nClose is safe because dev_deactivate_many() stops the qdisc first.\nbcmgenet_suspend() does not, so stop Tx NAPI before the queues on both\npaths.\n\nKASAN on a Raspberry Pi CM4, driven from an MTU change because suspend\nfreezes user space before the callback runs:\n\n BUG: KASAN: use-after-free in bcmgenet_xmit+0x17f8/0x2258\n Write of size 8 at addr ffffff8055844a68 by task ksoftirqd/0/14\n bcmgenet_xmit+0x17f8/0x2258\n dev_hard_start_xmit+0x13c/0x588\n sch_direct_xmit+0x108/0x340\n __dev_queue_xmit+0x1190/0x3848"
