The description of cve is:\n\n A flaw was found in the ATA over Ethernet (AoE) driver in the Linux\n kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on\n `struct net_device`, and a use-after-free can be triggered by racing\n between the free on the struct and the access through the `skbtxq`\n global queue. This could lead to a denial of service condition or\n potential code execution.\n\nIn aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial\ncode is finished. But the net_device ifp will still be used in\nlater tx()->dev_queue_xmit() in kthread. Which means that the\ndev_put(ifp) should NOT be called in the success path of skb\ninitial code in aoecmd_cfg_pkts(). Otherwise tx() may run into\nuse-after-free because the net_device is freed.\n\nThis patch removed the dev_put(ifp) in the success path in\naoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx()." } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [
