The bug is reached only through the local SIOCETHTOOL ETHTOOL_TEST ioctl path (__dev_ethtool \u2192 ethtool_self_test \u2192 i40e_diag_test \u2192 i40e_close/i40e_do_reset), not via remote packet processing or an adjacent-link protocol.\nAC:L - An attacker who can drive PF reset and immediately run ethtool -t controls both sides of the race; the multi-second RESET_RECOVERY_PENDING window (prep_for_reset without rtnl on the async service-task path, then rebuild) is large enough to hit reliably by issuing both operations back-to-back.\nPR:L - ETHTOOL_TEST requires ns_capable(net->user_ns, CAP_NET_ADMIN), which is available in a user-namespace\u2013owned netns with a delegated i40e PF, matching prior Intel ethernet/ethtool scoring (e.g. ice AF_XDP CAP_NET_ADMIN paths).\nUI:N - The attacker issues the ethtool self-test (and the concurrent reset trigger) from their own process; no separate victim action such as mounting media or opening a file is required.\nS:U - The race corrupts host-kernel i40e ring/VSI state within the same OS security authority and does not cross a VM, IOMMU, or sandbox boundary.\nC:H - Overlapping i40e_vsi_close calls free TX/RX resources outside the __I40E_VSI_DOWN bit (desc check then kfree(tx_bi)/dma_free_coherent with no serialization), yielding a heap double-free/UAF that can be leveraged for high-impact kernel memory disclosure.\nI:H - The same unsynchronized double-free/UAF of tx_bi and DMA descriptor memory is exploitable heap corruption that, per UAF guidance, enables write and control-flow hijack primitives beyond a pure crash.\nA:H - The race produces kernel call traces and panics (including WARN_ON(tx_ring->tx_bi) in i40e_setup_tx_descriptors and faults from the double-free/UAF), which is a full availability impact."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/intel/i40e/i40e_ethtool.c"], "versions": [{"version": "e17bc411aea8fbebc51857037f104ab09f765120", "lessThan": "5ba9956ca57e361fb13ea369bb753eb33177acc7", "status": "affected", "versionType": "git"}, {"version": "e17bc411aea8fbebc51857037f104ab09f765120", "lessThan": "15950157e2c24865b696db1c9ccc72743ae0e967", "status": "affected", "versionType": "git"}, {"version": "e17bc411aea8fbebc51857037f104ab09f765120", "lessThan": "ff6e03fe84bc917bb0c907d02de668c2fe101712", "status": "affected", "versionType": "git"}, {"version": "e17bc411aea8fbebc51857037f104ab09f765120", "lessThan": "814092927a215f5ca6c08249ec72a205e0b473cd", "status": "affected", "versionType": "git"}, {"version": "e17bc411aea8fbebc51857037f104ab09f765120", "lessThan": "0a4e5a3dc5e41212870e6043895ae02455c93f63", "status": "affected", "versionType": "git"}, {"version": "e17bc411aea8fbebc51857037f104ab09f765120", "lessThan": "322271351b0e41565171e4cce70ea41854fac115", "status": "affected", "versionType": "git"}, {"version": "e17bc411aea8fbebc51857037f104ab09f765120", "lessThan": "fd5855e6b1358e816710afee68a1d2bc685176ca", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/ethernet/intel/i40e/i40e_ethtool.c"], "versions": [{"version": "4.2", "status": "affected"}, {"version": "0", "lessThan": "4.2", "status": "unaffected", "versionType": "semver"}, {"version": "4.14.285", "lessThanOrEqual": "4.14.*", "status": "unaffected", "versionType": "semver"}, {"version": "4.19.249", "lessThanOrEqual": "4.19.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.4.200", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.124", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.49", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.18.6", "lessThanOrEqual": "5.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.19", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "4.14.285"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "4.19.249"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "5.4.200"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "5.10.124"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "5.15.49"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "5.18.6"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.2", "versionEndExcluding": "5.19"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/5ba9956ca57e361fb13ea369bb753eb33177acc7"}, {"url": "https://git.kernel.org/stable/c/15950157e2c24865b696db1c9ccc72743ae0e967"}, {"url": "https://git.kernel.org/stable/c/ff6e03fe84bc917bb0c907d02de668c2fe101712"}, {"url": "https://git.kernel.org/stable/c/814092927a215f5ca6c08249ec72a205e0b473cd"}, {"url": "https://git.kernel.org/stable/c/0a4e5a3dc5e41212870e6043895ae02455c93f63"}, {"url": "https://git.kernel.org/stable/c/322271351b0e41565171e4cce70ea41854fac115"}, {"url": "https://git.kernel.org/stable/c/fd5855e6b1358e816710afee68a1d2bc685176ca"}], "title": "i40e: Fix call trace in setup_tx_descriptors", "x_generator": {"engine": "bippy-1.2.0"}}}}
