Per kernel CNA guidance nfsd bugs are Network.\nAC:L - A single, fully attacker-controlled SETATTR RPC deterministically writes the label; there is no race, no memory-layout dependency, and no retry needed. The only precondition is the standard labeled-NFS deployment (CONFIG_NFSD_V4_SECURITY_LABEL plus the `security_label` export option), which is the configuration being scored.\nPR:N - The essence of the bug is that all permission checks are skipped: nfsd_permission() is invoked with an effective mask of 0 and the LSM relabel/CAP_MAC_ADMIN/ownership checks never run, so any asserted AUTH_SYS uid works \u2014 including the squashed anonymous uid. The attacker needs no account or credential on the server; export IP filtering and the reserved-port `secure` check are network-level controls, not privileges on the vulnerable component.\nUI:N - The attacker issues the RPC directly against the server; no administrator or user on the server has to open a file, mount anything, or take any action.\nS:U - The bypassed checks and the corrupted security labels are both enforced and consumed by the same kernel/LSM security authority on the NFS server; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - Arbitrary relabeling defeats the MAC confidentiality controls that are the primary protection on such systems \u2014 an MLS-labeled file can be dropped to a lower level, or a protected file relabeled to a type readable by an untrusted or attacker-influenced domain, and the httpd_sys_script_exec_t-style relabel yields code execution on the server with arbitrary read.\nI:H - An unauthenticated client can write arbitrary SELinux contexts or Smack labels onto any file in the export, bypassing inode_owner_or_capable(), FILE__RELABELFROM/RELABELTO policy, CAP_MAC_ADMIN, immutable/append-only flags, and root squashing \u2014 a complete compromise of security-critical metadata that can be escalated to code execution on the server.\nA:H - Relabeling files to a type or invalid context that legitimate confined domains cannot access denies those services their data and breaks them, and the same primitive escalates to code execution allowing the server to be rendered inoperable."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["security/selinux/hooks.c", "security/smack/smack_lsm.c"], "versions": [{"version": "18032ca062e621e15683cb61c066ef3dc5414a7b", "lessThan": "2dbc4b7bac60b02cc6e70d05bf6a7dfd551f9dda", "status": "affected", "versionType": "git"}, {"version": "18032ca062e621e15683cb61c066ef3dc5414a7b", "lessThan": "fe0cd53791119f6287b6532af8ce41576d664930", "status": "affected", "versionType": "git"}, {"version": "18032ca062e621e15683cb61c066ef3dc5414a7b", "lessThan": "eebec98791d0137e455cc006411bb92a54250924", "status": "affected", "versionType": "git"}, {"version": "18032ca062e621e15683cb61c066ef3dc5414a7b", "lessThan": "459584258d47ec3cc6245a82e8a49c9d08eb8b57", "status": "affected", "versionType": "git"}, {"version": "18032ca062e621e15683cb61c066ef3dc5414a7b", "lessThan": "f71ec019257ba4f7ab198bd948c5902a207bad96", "status": "affected", "versionType": "git"}, {"version": "18032ca062e621e15683cb61c066ef3dc5414a7b", "lessThan": "76a0e79bc84f466999fa501fce5bf7a07641b8a7", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["security/selinux/hooks.c", "security/smack/smack_lsm.c"], "versions": [{"version": "3.11", "status": "affected"}, {"version": "0", "lessThan": "3.11", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.227", "lessThanOrEqual": "5.10.*", "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": "6.6.49", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.10.8", "lessThanOrEqual": "6.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.11", "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": "3.11", "versionEndExcluding": "5.10.227"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "5.15.168"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.1.113"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.6.49"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.10.8"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.11", "versionEndExcluding": "6.11"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/2dbc4b7bac60b02cc6e70d05bf6a7dfd551f9dda"}, {"url": "https://git.kernel.org/stable/c/fe0cd53791119f6287b6532af8ce41576d664930"}, {"url": "https://git.kernel.org/stable/c/eebec98791d0137e455cc006411bb92a54250924"}, {"url": "https://git.kernel.org/stable/c/459584258d47ec3cc6245a82e8a49c9d08eb8b57"}, {"url": "https://git.kernel.org/stable/c/f71ec019257ba4f7ab198bd948c5902a207bad96"}, {"url": "https://git.kernel.org/stable/c/76a0e79bc84f466999fa501fce5bf7a07641b8a7"}], "title": "selinux,smack: don't bypass permissions check in inode_setsecctx hook", "x_generator": {"engine": "bippy-1.2.0"}}, "adp": [{"metrics": [{"other": {"type": "ssvc", "content": {"timestamp": "2024-09-29T15:05:47.775114Z", "id": "CVE-2024-46695", "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": "2024-09-29T15:06:01.561Z"}}, {"title": "CVE Program Container", "references": [{"url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"}, {"url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}], "providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2025-11-03T22:16:30.596Z"}}]}}

Dado que nfsd_setattr() es el \u00fanico consumidor de security_inode_setsecctx(), la soluci\u00f3n m\u00e1s sencilla parece ser reemplazar la llamada a __vfs_setxattr_noperm() con una llamada a __vfs_setxattr_locked(). Esto soluciona el problema anterior y tiene el beneficio adicional de hacer que nfsd recupere las delegaciones conflictivas en un archivo cuando un cliente intenta cambiar su etiqueta de seguridad."}], "id": "CVE-2024-46695", "lastModified": "2026-08-04T11:20:15.827", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 9.8, "baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "version": "3.1"}, "exploitabilityScore": 3.9, "impactScore": 5.9, "source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "type": "Secondary"}, {"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "NONE", "baseScore": 4.4, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "HIGH", "privilegesRequired": "HIGH", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:N", "version": "3.1"}, "exploitabilityScore": 0.8, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2024-46695", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "partial"}], "role": "CISA Coordinator", "timestamp": "2024-09-29T15:05:47.775114Z", "version": "2.0.3"}}]}, "published": "2024-09-13T06:15:14.320", "references": [{"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/2dbc4b7bac60b02cc6e70d05bf6a7dfd551f9dda"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/459584258d47ec3cc6245a82e8a49c9d08eb8b57"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/76a0e79bc84f466999fa501fce5bf7a07641b8a7"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/eebec98791d0137e455cc006411bb92a54250924"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "tags": ["Patch"], "url": "https://git.kernel.org/stable/c/f71ec019257ba4f7ab198bd948c5902a207bad96"}, {"source": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "url": "https://git.kernel.org/stable/c/fe0cd53791119f6287b6532af8ce41576d664930"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"}], "sourceIdentifier": "416baaa9-dc9f-4396-8d5f-8c081fb06d67", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-276"}], "source": "nvd@nist.gov", "type": "Primary"}]}
