Reaching it requires being on the same wireless segment, not the wider network.\nAC:L - On any device whose firmware advertises a SESSION_PROTECTION_CMD version differing from the SESSION_PROTECTION_NOTIF version, the mis-parse and resulting WARN are deterministic on every session-protection notification — the attacker simply forces re-association, which is fully under their control and repeatable.\nPR:N - An adjacent attacker sending deauthentication frames or operating a rogue AP needs no credentials or account on the victim system; the association path is entered automatically by the supplicant.\nUI:N - Stations auto-reconnect after being deauthenticated, so the association that schedules session protection — and thus the notification that trips the bug — occurs with no action by the device owner.\nS:U - The fault, the WARN, and the corrupted time-event state all remain inside the kernel's iwlwifi/mac80211 security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:N - Both index lookups are bounds-checked before any array dereference and the notification is a fixed-size struct, so there is no out-of-bounds read or other disclosure of memory contents to the attacker.\nI:L - Misinterpreting mac_id as link_id makes the handler operate on an unintended vif, overwriting that interface's time_event_data (running, end_jiffies, id, link_id) and forcing an unwarranted iwl_mvm_connection_loss(); this is limited, unauthorized modification of driver state, not an arbitrary write.\nA:H - The bug produces a WARNING splat in softirq/NAPI context, which panics the kernel outright when panic_on_warn is set, and otherwise breaks session protection so association fails or the existing connection is torn down — a repeatable denial of service on the Wi-Fi interface." } ] } ], "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/time-event.c" ], "versions": [ { "version": "085d33c53012866b6c088b69b603af7cf69c0a53", "lessThan": "222abd95f503e28c0404e596291fe472fe90929c", "status": "affected", "versionType": "git" }, { "version": "085d33c53012866b6c088b69b603af7cf69c0a53", "lessThan": "bbe806c294c9c4cd1221140d96e5f367673e393a", "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/time-event.c" ], "versions": [ { "version": "6.7", "status": "affected" }, { "version": "0", "lessThan": "6.7", "status": "unaffected", "versionType": "semver" }, { "version": "6.8.5", "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": "6.7", "versionEndExcluding": "6.8.5" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.7", "versionEndExcluding": "6.9" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/222abd95f503e28c0404e596291fe472fe90929c" }, { "url": "https://git.kernel.org/stable/c/bbe806c294c9c4cd1221140d96e5f367673e393a" } ], "title": "wifi: iwlwifi: mvm: pick the version of SESSION_PROTECTION_NOTIF", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "problemTypes": [ { "descriptions": [ { "type": "CWE", "lang": "en", "description": "CWE-noinfo Not enough information" } ] } ], "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 4.7, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "HIGH", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE" } }, { "other": { "type": "ssvc", "content": { "timestamp": "2024-05-29T18:22:09.105260Z", "id": "CVE-2024-35913", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2024-10-29T19:47:12.222Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T03:21:49.022Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/222abd95f503e28c0404e596291fe472fe90929c", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/bbe806c294c9c4cd1221140d96e5f367673e393a", "tags": [ "x_transferred" ] } ] } ] } }
