There is no network, adjacent-network, or removable-device path to the flaw.\nAC:L - The premature dma_free_coherent() happens deterministically on every teardown, and in the probe-failure path no stop command is ever sent so the firmware DMAs into the freed pages indefinitely; a local attacker can reliably shape which structures land on the recycled pages via memory pressure. Multiple independent reporters reproduced the corruption on stock systems.\nPR:L - The damaging state arises during automatic boot-time probe with no privileged action at all, and a basic local user can drive page reallocation into the stale-DMA target; no capability check gates the resulting memory corruption.\nUI:N - The probe error path executes from the driver's init workqueue during boot with no user present, and teardown-time frees need no victim action. Nothing must be opened, mounted, or clicked.\nS:U - The corrupted memory is ordinary kernel memory managed by the same security authority as the driver. dma_free_coherent() tears down any IOMMU mapping, so this is stale DMA on untranslated configurations rather than a DMA/IOMMU boundary bypass.\nC:H - Freed coherent pages return to the buddy allocator and can be handed to page cache, slab, or userspace, so the write-after-free corrupts arbitrary reallocated kernel objects and can be leveraged into disclosure of their contents. Sensor data is also deposited into whatever memory now owns those pages.\nI:H - The MP2 co-processor repeatedly writes 32 bytes into memory the kernel has reassigned, giving an uncontrolled kernel write primitive; reporters observed this propagate to persistent btrfs metadata corruption on disk.\nA:H - The stale DMA produced page faults, kernel memory errors, and btrfs filesystems forced read-only, i.e. system crashes and loss of filesystem availability." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/hid/amd-sfh-hid/amd_sfh_client.c" ], "versions": [ { "version": "4b2c53d93a4bc9d52cc0ec354629cfc9dc217f93", "lessThan": "8c6ad37e5882073cab84901a31da9cb22f316276", "status": "affected", "versionType": "git" }, { "version": "4b2c53d93a4bc9d52cc0ec354629cfc9dc217f93", "lessThan": "4cd9c5a0fcadc39a05c978a01e15e0d1edc4be93", "status": "affected", "versionType": "git" }, { "version": "4b2c53d93a4bc9d52cc0ec354629cfc9dc217f93", "lessThan": "1c3b4c90479aa0375ec98fe1a802993ff96a5f47", "status": "affected", "versionType": "git" }, { "version": "4b2c53d93a4bc9d52cc0ec354629cfc9dc217f93", "lessThan": "9dfee956f53eea96d93ef1e13ab4ce020f4c58b3", "status": "affected", "versionType": "git" }, { "version": "4b2c53d93a4bc9d52cc0ec354629cfc9dc217f93", "lessThan": "c56f9ecb7fb6a3a90079c19eb4c8daf3bbf514b3", "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/hid/amd-sfh-hid/amd_sfh_client.c" ], "versions": [ { "version": "5.11", "status": "affected" }, { "version": "0", "lessThan": "5.11", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.168", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.113", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.57", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.11.4", "lessThanOrEqual": "6.11.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12", "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": "5.11", "versionEndExcluding": "5.15.168" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "6.1.113" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "6.6.57" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "6.11.4" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.11", "versionEndExcluding": "6.12" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/8c6ad37e5882073cab84901a31da9cb22f316276" }, { "url": "https://git.kernel.org/stable/c/4cd9c5a0fcadc39a05c978a01e15e0d1edc4be93" }, { "url": "https://git.kernel.org/stable/c/1c3b4c90479aa0375ec98fe1a802993ff96a5f47" }, { "url": "https://git.kernel.org/stable/c/9dfee956f53eea96d93ef1e13ab4ce020f4c58b3" }, { "url": "https://git.kernel.org/stable/c/c56f9ecb7fb6a3a90079c19eb4c8daf3bbf514b3" } ], "title": "HID: amd_sfh: Switch to device-managed dmam_alloc_coherent()", "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-2024-50189", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2025-10-01T20:18:24.884215Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "description": "CWE-noinfo Not enough information" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-10-01T20:27:08.714Z" } }, { "title": "CVE Program Container", "references": [ { "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html" } ], "providerMetadata": { "orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:26:43.186Z" } } ] } }
