This matches the WiFi frame-injection = Adjacent guidance.\nAC:L - The attacker chooses the channel (non-DFS 5 GHz UNII-3 channels 149-165 map to the furthest out-of-bounds offsets), and client devices scan those channels automatically and repeatedly; the uninitialized-memory disclosure via survey dump is deterministic on every boot.\nPR:N - `wcn36xx_update_survey()` runs on every frame at RX time, before mac80211 authentication/association, so an unauthenticated attacker with no credentials on any network triggers it. The corresponding read path is exposed through `NL80211_CMD_GET_SURVEY`, which carries no admin-permission flag and is dumpable by any unprivileged local user.\nUI:N - No victim action is required — wpa_supplicant/NetworkManager background scanning hops through the affected 5 GHz channels automatically, and a device merely operating on such a channel writes out of bounds on every received frame.\nS:U - The heap corruption and information disclosure are confined to the kernel's own memory and security authority, with no crossing into a hypervisor, IOMMU, or other separate security scope.\nC:H - `wcn36xx_get_survey()` reads up to 38 bytes past the 39-byte allocation and returns the values to userspace via the unprivileged nl80211 survey dump, and the missing zeroing leaks uninitialized kernel heap contents; the out-of-bounds access also provides a lever for broader disclosure.\nI:H - Received frames on high 5 GHz channels write attacker-influenced RSSI/SNR bytes at offsets 64-77 of a 39-byte allocation, corrupting the adjacent slab object — a heap out-of-bounds write, which scores High per the guidance.\nA:H - Corrupting neighbouring heap objects (and tripping KASAN/redzone or slab metadata checks) causes kernel oops or panic, and the write is triggerable repeatedly by any nearby unauthenticated transmitter." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/net/wireless/ath/wcn36xx/main.c" ], "versions": [ { "version": "29696e0aa413b9d56558731aae3806d7cff48d36", "lessThan": "ae68efdff7a7a42ab251cac79d8713de6f0dbaa0", "status": "affected", "versionType": "git" }, { "version": "29696e0aa413b9d56558731aae3806d7cff48d36", "lessThan": "e95f9c408ff8311f75eeabc8acf34a66670d8815", "status": "affected", "versionType": "git" }, { "version": "29696e0aa413b9d56558731aae3806d7cff48d36", "lessThan": "64c4dcaeac1dc1030e47883b04a617ca9a4f164e", "status": "affected", "versionType": "git" }, { "version": "29696e0aa413b9d56558731aae3806d7cff48d36", "lessThan": "34cd2817708aec51ef1a6c007e0d6d5342a025d7", "status": "affected", "versionType": "git" }, { "version": "29696e0aa413b9d56558731aae3806d7cff48d36", "lessThan": "6200d947f050efdba4090dfefd8a01981363d954", "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/ath/wcn36xx/main.c" ], "versions": [ { "version": "5.18", "status": "affected" }, { "version": "0", "lessThan": "5.18", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.129", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.76", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.13", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13.2", "lessThanOrEqual": "6.13.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.14", "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": "5.18", "versionEndExcluding": "6.1.129" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.6.76" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.12.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.13.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.18", "versionEndExcluding": "6.14" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/ae68efdff7a7a42ab251cac79d8713de6f0dbaa0" }, { "url": "https://git.kernel.org/stable/c/e95f9c408ff8311f75eeabc8acf34a66670d8815" }, { "url": "https://git.kernel.org/stable/c/64c4dcaeac1dc1030e47883b04a617ca9a4f164e" }, { "url": "https://git.kernel.org/stable/c/34cd2817708aec51ef1a6c007e0d6d5342a025d7" }, { "url": "https://git.kernel.org/stable/c/6200d947f050efdba4090dfefd8a01981363d954" } ], "title": "wifi: wcn36xx: fix channel survey memory allocation size", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 5.5, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "NONE" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2024-57997", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2025-10-01T19:31:20.546897Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-908", "description": "CWE-908 Use of Uninitialized Resource" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T19:36:42.332Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00028.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T19:33:08.950Z" } } ] } }
