Title
aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts
Summary
In the Linux kernel, the following vulnerability has been resolved:
aoe: fix the potential use-after-free problem in aoecmd_cfg_pkts
This patch is against CVE-2023-6270. The description of cve is:
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux
kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on
`struct net_device`, and a use-after-free can be triggered by racing
between the free on the struct and the access through the `skbtxq`
global queue. This could lead to a denial of service condition or
potential code execution.
In aoecmd_cfg_pkts(), it always calls dev_put(ifp) when skb initial
code is finished. But the net_device ifp will still be used in
later tx()->dev_queue_xmit() in kthread. Which means that the
dev_put(ifp) should NOT be called in the success path of skb
initial code in aoecmd_cfg_pkts(). Otherwise tx() may run into
use-after-free because the net_device is freed.
This patch removed the dev_put(ifp) in the success path in
aoecmd_cfg_pkts(), and added dev_put() after skb xmit in tx().

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()-\u003edev_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().\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"4.19.311\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.4.273\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.214\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.153\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.83\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.23\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.7.11\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.8.2\", \"versionStartIncluding\": \"2.6.22\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.9\", \"versionStartIncluding\": \"2.6.22\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2026-05-11T20:06:33.344Z\"}}}",
