no remote or adjacent 802.11 frame drives the vulnerable path directly.\nAC:L - There is no race and no memory-layout dependency; once a firmware/DP init error has occurred the stale `dp->spt_info` is deterministic, and the reporter notes it is \"always reproducible from a VM\" where MSI addressing initialization reliably fails.\nPR:L - The `ath12k_core_reconfigure_on_crash()` path reaches the second `ath12k_dp_cc_cleanup()` with no privilege at all after two failed recovery cycles, and the CNA scored the directly analogous ath12k error-path dangling-pointer bug (CVE-2025-38116) at PR:L rather than PR:H.\nUI:N - The triggering action is the attacker's own unbind/module-removal or the driver's automatic recovery worker; no separate victim needs to be induced to do anything.\nS:U - The freed memory, the stale pointer, and the fault are all within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The root cause is a retained pointer to freed kmalloc'd memory whose contents are re-read on the second cleanup (`dp->spt_info[i].vaddr/paddr`); an attacker who reclaims that slab allocation controls the values read, giving a heap-content disclosure primitive.\nI:H - Operating on the freed `spt_info` array feeds attacker-groomable heap contents into `dma_free_coherent()`, yielding a double-free of DMA coherent mappings — memory corruption leverageable beyond a simple crash.\nA:H - The immediate result is a kernel oops (NULL dereference at offset 0x20) taken while `dp->rx_desc_lock` is held with BH disabled, so the spinlock is never released and any later taker deadlocks — a hard denial of service." } ] } ], "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/dp.c" ], "versions": [ { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "81da9c0854545c3188ca2a09afe7cb65f9c012b5", "status": "affected", "versionType": "git" }, { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "2eec88c0fa63f8ad35704a8c9df0b5bd8694fcda", "status": "affected", "versionType": "git" }, { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "488d2959c28621e52b3cce118a813a4bc18bb3d1", "status": "affected", "versionType": "git" }, { "version": "d889913205cf7ebda905b1e62c5867ed4e39f6c2", "lessThan": "1304446f67863385dc4c914b6e0194f6664ee764", "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/dp.c" ], "versions": [ { "version": "6.3", "status": "affected" }, { "version": "0", "lessThan": "6.3", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.64", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.11", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.2", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13", "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": "6.6.64" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.11.11" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.12.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.3", "versionEndExcluding": "6.13" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/81da9c0854545c3188ca2a09afe7cb65f9c012b5" }, { "url": "https://git.kernel.org/stable/c/2eec88c0fa63f8ad35704a8c9df0b5bd8694fcda" }, { "url": "https://git.kernel.org/stable/c/488d2959c28621e52b3cce118a813a4bc18bb3d1" }, { "url": "https://git.kernel.org/stable/c/1304446f67863385dc4c914b6e0194f6664ee764" } ], "title": "wifi: ath12k: fix crash when unbinding", "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-2024-53188", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2025-10-01T20:04:13.907854Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-476", "description": "CWE-476 NULL Pointer Dereference" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T20:07:21.292Z" } } ] } }
