for PCIe-integrated ath12k this is a local device/firmware trust-boundary path.\nAC:L - Firmware fully controls both the u32 phy_id index and the ~40-byte reg_cap payload written into soc->hal_reg_cap[]; once a crafted SERVICE_READY_EXT is supplied the out-of-bounds store is deterministic with no race or layout dependency.\nPR:N - The vulnerable parser runs automatically on probe/reconfigure when consuming device firmware WMI with no OS credential, capability, or authentication check on the path.\nUI:N - ath12k_core_start() waits for SERVICE_READY_EXT during normal bring-up and crash recovery; no victim user action such as opening a file or configuring the interface is required.\nS:U - The out-of-bounds write corrupts ath12k_base fields in the host kernel and does not cross a VM, IOMMU, or other separate security authority.\nC:H - An attacker-controlled index writes past hal_reg_cap[MAX_RADIOS] into adjacent kernel state (including peers list heads and related driver objects), which is memory corruption reasonably leveraged for high confidentiality impact.\nI:H - This is an out-of-bounds kernel write of firmware-controlled contents at a firmware-chosen index, enabling corruption of adjacent control data and potential control-flow hijack.\nA:H - Corrupting adjacent ath12k_base fields (list heads, readiness flags, pointers) can cause kernel oops/panic or wedge the driver, so availability impact is high." } ] } ], "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/ath12k/wmi.c" ], "versions": [ { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "dfe13eaab043130f90dd3d57c7d88577c04adc97", "status": "affected", "versionType": "git" }, { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "4dd0547e8b45faf6f95373be5436b66cde326c0e", "status": "affected", "versionType": "git" }, { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "b302dce3d9edea5b93d1902a541684a967f3c63c", "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/ath12k/wmi.c" ], "versions": [ { "version": "6.3", "status": "affected" }, { "version": "0", "lessThan": "6.3", "status": "unaffected", "versionType": "semver" }, { "version": "6.5.13", "lessThanOrEqual": "6.5.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.3", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.7", "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": "6.3", "versionEndExcluding": "6.5.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.6.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.7" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/dfe13eaab043130f90dd3d57c7d88577c04adc97" }, { "url": "https://git.kernel.org/stable/c/4dd0547e8b45faf6f95373be5436b66cde326c0e" }, { "url": "https://git.kernel.org/stable/c/b302dce3d9edea5b93d1902a541684a967f3c63c" } ], "title": "wifi: ath12k: fix possible out-of-bound write in ath12k_wmi_ext_hal_reg_caps()", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "problemTypes": [ { "descriptions": [ { "type": "CWE", "cweId": "CWE-787", "lang": "en", "description": "CWE-787 Out-of-bounds Write" } ] } ], "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 6.2, "attackVector": "LOCAL", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H", "integrityImpact": "NONE", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "NONE", "confidentialityImpact": "NONE" } }, { "other": { "type": "ssvc", "content": { "timestamp": "2024-06-17T17:36:39.580141Z", "id": "CVE-2023-52829", "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": "2024-12-04T18:02:43.447Z" } }, { "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T23:11:36.065Z" }, "title": "CVE Program Container", "references": [ { "url": "https://git.kernel.org/stable/c/dfe13eaab043130f90dd3d57c7d88577c04adc97", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/4dd0547e8b45faf6f95373be5436b66cde326c0e", "tags": [ "x_transferred" ] }, { "url": "https://git.kernel.org/stable/c/b302dce3d9edea5b93d1902a541684a967f3c63c", "tags": [ "x_transferred" ] } ] } ] } }
