Wi-Fi driver reachability is Adjacent, consistent with other iwlwifi mvm CVEs.\nAC:L - Reaching the invalid-STA-ID removal requires the driver to be in an error/teardown state, but an adjacent attacker can drive repeated PASN responder add/remove churn and induce firmware command failures and FW restarts, so the triggering conditions are within attacker influence rather than beyond it.\nPR:N - PASN ranging is negotiated with unassociated peers before any credentials are established, so an adjacent 802.11 device needs no account or privilege on the target; FTM responder mode being enabled is an environmental precondition, not an attacker privilege.\nUI:N - The FTM responder teardown and firmware-restart paths run autonomously in the driver; no action by a local user or administrator is needed once the responder is configured.\nS:U - The out-of-bounds accesses corrupt memory inside the kernel's own iwlwifi driver state, staying entirely within the kernel security authority with no crossing into a hypervisor, IOMMU, or sandbox boundary.\nC:H - The bug performs an out-of-bounds read of fw_id_to_mac_id[0xFF] and two out-of-bounds writes that silently corrupt live struct iwl_mvm state adjacent to the RCU firmware-station tables; such kernel memory corruption around pointer tables is leverageable toward disclosure of kernel memory.\nI:H - Two out-of-bounds writes zero 8 bytes each ~2 KB past the fw_id_to_mac_id and fw_id_to_link_sta arrays, overwriting unrelated live driver fields inside struct iwl_mvm, and an invalid station ID is fed to firmware — an out-of-bounds write is a memory-corruption integrity impact.\nA:H - Nulling arbitrary driver fields leads to later NULL dereferences and oopses, the stale OOB-read value causes a STA_REMOVE_CMD with sta_id 0xFF to be sent to firmware which can assert and force a device reset, and the post-fix WARN_ON confirms this is a fatal-state condition." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/intel/iwlwifi/mvm/mld-sta.c" ], "versions": [ { "version": "006c152ac9e56ac7871efa995854c3ff8cf6915a", "lessThan": "94f80a8ec15e238b78521f20f8afaed60521a294", "status": "affected", "versionType": "git" }, { "version": "006c152ac9e56ac7871efa995854c3ff8cf6915a", "lessThan": "fab21d220017daa5fd8a3d788ff25ccfecfaae2f", "status": "affected", "versionType": "git" }, { "version": "006c152ac9e56ac7871efa995854c3ff8cf6915a", "lessThan": "17f64517bf5c26af56b6c3566273aad6646c3c4f", "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/wireless/intel/iwlwifi/mvm/mld-sta.c" ], "versions": [ { "version": "6.4", "status": "affected" }, { "version": "0", "lessThan": "6.4", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.31", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.10", "lessThanOrEqual": "6.8.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.9", "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": "6.4", "versionEndExcluding": "6.6.31" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.8.10" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.4", "versionEndExcluding": "6.9" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/94f80a8ec15e238b78521f20f8afaed60521a294" }, { "url": "https://git.kernel.org/stable/c/fab21d220017daa5fd8a3d788ff25ccfecfaae2f" }, { "url": "https://git.kernel.org/stable/c/17f64517bf5c26af56b6c3566273aad6646c3c4f" } ], "title": "wifi: iwlwifi: mvm: guard against invalid STA ID on removal", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T03:43:49.860Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/94f80a8ec15e238b78521f20f8afaed60521a294", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/fab21d220017daa5fd8a3d788ff25ccfecfaae2f", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/17f64517bf5c26af56b6c3566273aad6646c3c4f", "tags": [ "x_transferred" ] } ] }, { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2024-36921", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2024-09-10T17:16:04.083562Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-09-11T17:35:00.174Z" } } ] } }
