Per kernel WiFi guidance, frame-driven driver bugs are Adjacent, not Network or Local.\nAC:L - An adjacent attacker can reliably elicit PPDU status/CFO parsing by sending on-channel OFDM traffic, and mac_id is an 8-bit RX descriptor field while the arrays are only size 64 (also RTW89_MAX_MAC_ID_NUM is 128). SoftAP multi-station or HW-reported values \u226564 (observed index 188) hit the OOB write without an attacker-uncontrollable race.\nPR:N - The vulnerable path runs in driver RX interrupt/NAPI context with no authentication or capability check. An adjacent WiFi peer needs no account or privileges on the victim host.\nUI:N - Once the rtw89 interface is operating, PPDU status and CFO parsing run automatically on received frames. The attacker does not need the victim to mount, open a device, or accept a prompt.\nS:U - Impact is memory corruption inside the same host kernel WiFi driver authority. This is not a VM escape, IOMMU bypass, or other cross-boundary break.\nC:H - Unchecked mac_id indexes cfo_tail[]/cfo_cnt[] and can write past rtw89_cfo_tracking_info into adjacent rtw89_dev state. That kernel memory corruption is defensibly leveraged for disclosure primitives, so confidentiality is High.\nI:H - This is a confirmed out-of-bounds write (cfo_tail[macid] += cfo_val and cfo_cnt[macid]++), which is High integrity impact under kernel OOB-write guidance and can yield write/control-flow primitives.\nA:H - Out-of-bounds writes into driver/device state can oops or panic the kernel in IRQ/NAPI context, and repeated adjacent triggering can cause reliable denial of service even without full exploitation."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/net/wireless/realtek/rtw89/phy.c"], "versions": [{"version": "e3ec7017f6a20d12ddd9fe23d345ebb7b8c104dd", "lessThan": "03ed236480aeec8c2fd327a1ea6d711364c495e3", "status": "affected", "versionType": "git"}, {"version": "e3ec7017f6a20d12ddd9fe23d345ebb7b8c104dd", "lessThan": "c32fafe68298bb599e825c298e1d0ba30186f0a5", "status": "affected", "versionType": "git"}, {"version": "e3ec7017f6a20d12ddd9fe23d345ebb7b8c104dd", "lessThan": "97df85871a5b187609d30fca6d85b912d9e02f29", "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/realtek/rtw89/phy.c"], "versions": [{"version": "5.16", "status": "affected"}, {"version": "0", "lessThan": "5.16", "status": "unaffected", "versionType": "semver"}, {"version": "5.17.14", "lessThanOrEqual": "5.17.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.18.3", "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": "5.16", "versionEndExcluding": "5.17.14"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.16", "versionEndExcluding": "5.18.3"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.16", "versionEndExcluding": "5.19"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/03ed236480aeec8c2fd327a1ea6d711364c495e3"}, {"url": "https://git.kernel.org/stable/c/c32fafe68298bb599e825c298e1d0ba30186f0a5"}, {"url": "https://git.kernel.org/stable/c/97df85871a5b187609d30fca6d85b912d9e02f29"}], "title": "rtw89: cfo: check mac_id to avoid out-of-bounds", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"metrics": [{"cvssV3_1": {"scope": "UNCHANGED", "version": "3.1", "baseScore": 7.8, "attackVector": "LOCAL", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH"}}, {"other": {"type": "ssvc", "content": {"id": "CVE-2022-49471", "role": "CISA Coordinator", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "total"}], "version": "2.0.3", "timestamp": "2025-10-01T19:39:49.476327Z"}}}], "problemTypes": [{"descriptions": [{"lang": "en", "type": "CWE", "cweId": "CWE-129", "description": "CWE-129 Improper Validation of Array Index"}]}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T19:46:46.352Z"}}]}}
