There is no network-facing path into `mi_enum_attr()`.\nAC:L - The attacker fully controls every field involved (`rec->attr_off`, `rec->used`, `rec->total`, `attr->size`) and the overread is deterministic on the first attribute enumeration \u2014 no race, timing window, or uncontrolled memory-layout condition is involved.\nPR:L - An unprivileged local user can get an arbitrary NTFS image mounted on common desktop/kiosk configurations via udisks2/systemd automount of removable media, or via `user`-option/loop mounts; no root in the initial namespace is needed for the realistic scenario.\nUI:N - In the highest-impact scenario the attacker supplies and mounts the malicious volume themselves (inserting media that is auto-mounted, or loop-mounting their own image), so no action by a separate victim is required.\nS:U - The out-of-bounds access stays within the kernel's own memory and security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `attr->size` is dereferenced at an attacker-influenced offset beyond the `kmalloc()`ed MFT record buffer, reading adjacent kernel heap contents; the commit's own framing is that attributes could \"stray beyond valid memory region\", so the read is not reliably bounded.\nI:N - The defect is purely a read of `attr->size`; the surviving `off + asize > used` boundary test still constrains any attribute handed back to callers, so no out-of-bounds write or control-flow corruption primitive arises.\nA:H - The out-of-bounds dereference can hit an unmapped page or trip KASAN/hardened-allocator checks, producing a kernel oops or panic and denying service to the whole system."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["fs/ntfs3/record.c"], "versions": [{"version": "4534a70b7056fd4b9a1c6db5a4ce3c98546b291e", "lessThan": "386613a44b858304a88529ade2ccc1e079a5fc56", "status": "affected", "versionType": "git"}, {"version": "4534a70b7056fd4b9a1c6db5a4ce3c98546b291e", "lessThan": "22cdf3be7d34f61a91b9e2966fec3a29f3871398", "status": "affected", "versionType": "git"}, {"version": "4534a70b7056fd4b9a1c6db5a4ce3c98546b291e", "lessThan": "809f9b419c75f8042c58434d2bfe849140643e9d", "status": "affected", "versionType": "git"}, {"version": "4534a70b7056fd4b9a1c6db5a4ce3c98546b291e", "lessThan": "556bdf27c2dd5c74a9caacbe524b943a6cd42d99", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["fs/ntfs3/record.c"], "versions": [{"version": "5.15", "status": "affected"}, {"version": "0", "lessThan": "5.15", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.120", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.60", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.11.7", "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": "5.15", "versionEndExcluding": "6.1.120"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.6.60"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.11.7"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "5.15", "versionEndExcluding": "6.12"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/386613a44b858304a88529ade2ccc1e079a5fc56"}, {"url": "https://git.kernel.org/stable/c/22cdf3be7d34f61a91b9e2966fec3a29f3871398"}, {"url": "https://git.kernel.org/stable/c/809f9b419c75f8042c58434d2bfe849140643e9d"}, {"url": "https://git.kernel.org/stable/c/556bdf27c2dd5c74a9caacbe524b943a6cd42d99"}], "title": "ntfs3: Add bounds checking to mi_enum_attr()", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"title": "CVE Program Container", "references": [{"url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"}], "providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T20:44:37.543Z"}}]}}
