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()." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Linux", "product": { "product_data": [ { "product_name": "Linux", "version": { "version_data": [ { "version_affected": "<", "version_name": "7562f876cd93", "version_value": "ad80c34944d7" }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "2.6.22", "status": "affected" }, { "version": "0", "lessThan": "2.6.22", "status": "unaffected", "versionType": "semver" }, { "version": "4.19.311", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.273", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.214", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.153", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.83", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.23", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7.11", "lessThanOrEqual": "6.7.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.2", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix" } ], "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://git.kernel.org/stable/c/ad80c34944d7175fa1f5c7a55066020002921a99", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/ad80c34944d7175fa1f5c7a55066020002921a99" }, { "url": "https://git.kernel.org/stable/c/1a54aa506b3b2f31496731039e49778f54eee881", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/1a54aa506b3b2f31496731039e49778f54eee881" }, { "url": "https://git.kernel.org/stable/c/faf0b4c5e00bb680e8e43ac936df24d3f48c8e65", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/faf0b4c5e00bb680e8e43ac936df24d3f48c8e65" }, { "url": "https://git.kernel.org/stable/c/7dd09fa80b0765ce68bfae92f4e2f395ccf0fba4", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/7dd09fa80b0765ce68bfae92f4e2f395ccf0fba4" }, { "url": "https://git.kernel.org/stable/c/74ca3ef68d2f449bc848c0a814cefc487bf755fa", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/74ca3ef68d2f449bc848c0a814cefc487bf755fa" }, { "url": "https://git.kernel.org/stable/c/eb48680b0255a9e8a9bdc93d6a55b11c31262e62", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/eb48680b0255a9e8a9bdc93d6a55b11c31262e62" }, { "url": "https://git.kernel.org/stable/c/079cba4f4e307c69878226fdf5228c20aa1c969c", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/079cba4f4e307c69878226fdf5228c20aa1c969c" }, { "url": "https://git.kernel.org/stable/c/a16fbb80064634b254520a46395e36b87ca4731e", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/a16fbb80064634b254520a46395e36b87ca4731e" }, { "url": "https://git.kernel.org/stable/c/f98364e926626c678fb4b9004b75cacf92ff0662", "refsource": "MISC", "name": "https://git.kernel.org/stable/c/f98364e926626c678fb4b9004b75cacf92ff0662" } ] }, "generator": { "engine": "bippy-9e1c9544281a" } }
