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().\n\n## Affected\n\n- `linux_kernel >= 2.6.22, < 4.19.311`\n- `linux_kernel >= 4.20, < 5.4.273`\n- `linux_kernel >= 5.5, < 5.10.214`\n- `linux_kernel >= 5.11, < 5.15.153`\n- `linux_kernel >= 5.16, < 6.1.83`\n- `linux_kernel >= 6.2, < 6.6.23`\n- `linux_kernel >= 6.7, < 6.7.11`\n- `linux_kernel >= 6.8, < 6.8.2`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 6.8.2`","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
