The nvme-tcp host processes TCP PDUs and AENs from a remote NVMe-oF target; a malicious or compromised target triggers error recovery and async-event work via network protocol messages on an established connection.\nAC:L - The remote peer controls both sides of the race by sending an AEN (scheduling async_event_work) and inducing a transport error or disconnect (scheduling error_recovery_work), so success does not depend on conditions outside the attacker’s influence.\nPR:N - Exploitation requires no privileges on the victim host; once an NVMe-TCP session exists, an unauthenticated remote peer can trigger the race solely through fabric protocol behavior.\nUI:N - No additional user action is required at exploit time beyond a pre-existing NVMe-TCP controller connection typical of datacenter storage attachments with autoconnect/reconnect.\nS:U - The use-after-free corrupts kernel memory in the local host’s nvme-tcp driver and does not cross a distinct security authority such as a VM or IOMMU boundary.\nC:H - Use-after-free of the admin queue async-event resources and related queue/socket structures enables heap reuse and arbitrary kernel read primitives.\nI:H - The same UAF is exploitable for heap spraying and arbitrary write/control-flow hijacking in kernel context via the freed queue socket and async request objects.\nA:H - The UAF can cause kernel oops/panic or hangs during admin-queue teardown even without a full exploit, and can be repeated across automatic reconnects." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/nvme/host/tcp.c" ], "versions": [ { "version": "3f2304f8c6d6ed97849057bd16fee99e434ca796", "lessThan": "61a26ffd5ad3ece456d74c4c79f7b5e3f440a141", "status": "affected", "versionType": "git" }, { "version": "3f2304f8c6d6ed97849057bd16fee99e434ca796", "lessThan": "e192184cf8bce8dd55d619f5611a2eaba996fa05", "status": "affected", "versionType": "git" }, { "version": "3f2304f8c6d6ed97849057bd16fee99e434ca796", "lessThan": "5e42fca37ccc76f39f73732661bd47254cad5982", "status": "affected", "versionType": "git" }, { "version": "3f2304f8c6d6ed97849057bd16fee99e434ca796", "lessThan": "bb0d8fb35c4ff00a503c2c4dca4cce8d102a21c4", "status": "affected", "versionType": "git" }, { "version": "3f2304f8c6d6ed97849057bd16fee99e434ca796", "lessThan": "ff9fc7ebf5c06de1ef72a69f9b1ab40af8b07f9e", "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/nvme/host/tcp.c" ], "versions": [ { "version": "5.0", "status": "affected" }, { "version": "0", "lessThan": "5.0", "status": "unaffected", "versionType": "semver" }, { "version": "5.4.181", "lessThanOrEqual": "5.4.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.102", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.25", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.16.11", "lessThanOrEqual": "5.16.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.17", "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": "5.0", "versionEndExcluding": "5.4.181" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.0", "versionEndExcluding": "5.10.102" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.0", "versionEndExcluding": "5.15.25" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.0", "versionEndExcluding": "5.16.11" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.0", "versionEndExcluding": "5.17" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/61a26ffd5ad3ece456d74c4c79f7b5e3f440a141" }, { "url": "https://git.kernel.org/stable/c/e192184cf8bce8dd55d619f5611a2eaba996fa05" }, { "url": "https://git.kernel.org/stable/c/5e42fca37ccc76f39f73732661bd47254cad5982" }, { "url": "https://git.kernel.org/stable/c/bb0d8fb35c4ff00a503c2c4dca4cce8d102a21c4" }, { "url": "https://git.kernel.org/stable/c/ff9fc7ebf5c06de1ef72a69f9b1ab40af8b07f9e" } ], "title": "nvme-tcp: fix possible use-after-free in transport error_recovery work", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-03T15:25:01.577Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/61a26ffd5ad3ece456d74c4c79f7b5e3f440a141", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/e192184cf8bce8dd55d619f5611a2eaba996fa05", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/5e42fca37ccc76f39f73732661bd47254cad5982", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/bb0d8fb35c4ff00a503c2c4dca4cce8d102a21c4", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/ff9fc7ebf5c06de1ef72a69f9b1ab40af8b07f9e", "tags": [ "x_transferred" ] } ] }, { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2022-48789", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-09-10T16:59:42.520787Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-11T17:34:15.954Z" } } ] } }
