heap grooming to control the reallocated object is standard.\nPR:N - An adjacent 802.11 attacker needs no credentials on the target — background scans and auto-connect to a spoofed known SSID reach the path pre-authentication, and no local account or capability is required.\nUI:N - Background scanning across radios and auto-reconnect to saved networks occur without any user action, and CSA/band-steering frames are processed automatically by the connected station.\nS:U - The freed object, the corrupted structures and the resulting code execution all reside in the kernel's own security authority; no VM, IOMMU or sandbox boundary is crossed.\nC:H - Taking the `goto flush` branch runs `ath12k_mac_vif_cache_flush()` on the freed arvif, using freed bytes as `arvif->link_id` to index `ahvif->cache[]` and returning `arvif->ar` from freed memory for the caller to dereference — an out-of-bounds/arbitrary read primitive over kernel memory.\nI:H - The same use-after-free path performs writes through freed-memory-derived pointers (`ath12k_mac_bss_info_changed()`, `ath12k_mac_conf_tx()`, key-cache flush, and the caller's `arvif->punct_bitmap` store), giving a heap-spray-controlled write primitive suitable for control-flow hijack.\nA:H - Dereferencing freed and reallocated memory as pointers reliably produces a kernel oops/panic even when not exploited further, taking down the affected system." } ] } ], "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/mac.c" ], "versions": [ { "version": "b5068bc9180d06a5ac242b0f9263047c14f86211", "lessThan": "57100b87c77818cb0d582a92e5cb32fff85c757d", "status": "affected", "versionType": "git" }, { "version": "b5068bc9180d06a5ac242b0f9263047c14f86211", "lessThan": "f3a95a312419e4f1e992525917da9dbcd247038f", "status": "affected", "versionType": "git" }, { "version": "b5068bc9180d06a5ac242b0f9263047c14f86211", "lessThan": "5a10971c7645a95f5d5dc23c26fbac4bf61801d0", "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/mac.c" ], "versions": [ { "version": "6.10", "status": "affected" }, { "version": "0", "lessThan": "6.10", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.57", "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": "6.10", "versionEndExcluding": "6.12.57" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.13.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.10", "versionEndExcluding": "6.14" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/57100b87c77818cb0d582a92e5cb32fff85c757d" }, { "url": "https://git.kernel.org/stable/c/f3a95a312419e4f1e992525917da9dbcd247038f" }, { "url": "https://git.kernel.org/stable/c/5a10971c7645a95f5d5dc23c26fbac4bf61801d0" } ], "title": "wifi: ath12k: fix read pointer after free in ath12k_mac_assign_vif_to_vdev()", "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-2024-57995", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "version": "2.0.3", "timestamp": "2025-10-01T19:31:23.714588Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-416", "description": "CWE-416 Use After Free" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T19:36:42.461Z" } } ] } }
