A malicious Ceph monitor or OSD can deliver a crafted CEPH_MSG_OSD_MAP over TCP to an active CephFS or RBD kernel client.\nAC:L - Attacker-controlled envelope lengths, counts, and string lengths deterministically drive decoding beyond the message buffer without a race or other uncontrollable condition.\nPR:N - No privileges on the client host are required, and legacy monitor transport can dispatch OSD maps before the separate monitor authentication completes; auth_none deployments are also reachable.\nUI:N - Once the Ceph client is active, the peer can push the corrupted map without any user action.\nS:U - The vulnerability and resulting kernel-memory or availability impacts remain within the client host's kernel security authority.\nC:H - The decoder can perform repeated attacker-steered 1-, 4-, and 8-byte reads at unbounded offsets beyond the kvmalloc-backed network-message buffer.\nI:N - The vulnerable function only reads or skips input and writes decoded values into valid pool fields; it provides no out-of-bounds write, UAF, or control-flow corruption primitive.\nA:H - Large attacker-controlled pointer advances can cause a kernel page fault or oops, and repeated malicious maps can crash or render the client unusable." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "net/ceph/osdmap.c" ], "versions": [ { "version": "4f6a7e5ee1393ec4b243b39dac9f36992d161540", "lessThan": "d061be4c8040ffb1110d537654a038b8b6ad39d2", "status": "affected", "versionType": "git" }, { "version": "4f6a7e5ee1393ec4b243b39dac9f36992d161540", "lessThan": "145d140abda80e33331c5781d6603014fa75d258", "status": "affected", "versionType": "git" }, { "version": "4f6a7e5ee1393ec4b243b39dac9f36992d161540", "lessThan": "c82e39ff67353a5a6cbc07b786b8690bd2c45aaa", "status": "affected", "versionType": "git" }, { "version": "4f6a7e5ee1393ec4b243b39dac9f36992d161540", "lessThan": "e927ab132b87ba3f076705fc2684d94b24201ed1", "status": "affected", "versionType": "git" }, { "version": "4f6a7e5ee1393ec4b243b39dac9f36992d161540", "lessThan": "5d0d8c292531fe356c4e94dcfdf7d7212aca9957", "status": "affected", "versionType": "git" }, { "version": "4f6a7e5ee1393ec4b243b39dac9f36992d161540", "lessThan": "2acb8517429ab42146c6c0ac1daed1f03d2fd125", "status": "affected", "versionType": "git" }, { "version": "4f6a7e5ee1393ec4b243b39dac9f36992d161540", "lessThan": "8c738512714e8c0aa18f8a10c072d5b01c83db39", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "net/ceph/osdmap.c" ], "versions": [ { "version": "3.9", "status": "affected" }, { "version": "0", "lessThan": "3.9", "status": "unaffected", "versionType": "semver" }, { "version": "5.10.248", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.198", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.160", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.6.120", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.64", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.18.3", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.19", "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": "3.9", "versionEndExcluding": "5.10.248" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.9", "versionEndExcluding": "5.15.198" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.9", "versionEndExcluding": "6.1.160" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.9", "versionEndExcluding": "6.6.120" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.9", "versionEndExcluding": "6.12.64" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.9", "versionEndExcluding": "6.18.3" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.9", "versionEndExcluding": "6.19" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/d061be4c8040ffb1110d537654a038b8b6ad39d2" }, { "url": "https://git.kernel.org/stable/c/145d140abda80e33331c5781d6603014fa75d258" }, { "url": "https://git.kernel.org/stable/c/c82e39ff67353a5a6cbc07b786b8690bd2c45aaa" }, { "url": "https://git.kernel.org/stable/c/e927ab132b87ba3f076705fc2684d94b24201ed1" }, { "url": "https://git.kernel.org/stable/c/5d0d8c292531fe356c4e94dcfdf7d7212aca9957" }, { "url": "https://git.kernel.org/stable/c/2acb8517429ab42146c6c0ac1daed1f03d2fd125" }, { "url": "https://git.kernel.org/stable/c/8c738512714e8c0aa18f8a10c072d5b01c83db39" } ], "title": "libceph: make decode_pool() more resilient against corrupted osdmaps", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "id": "CVE-2025-71116", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "partial" } ], "version": "2.0.3", "timestamp": "2026-06-10T20:42:27.725166Z" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-06-11T18:44:23.486Z" } } ] } }
