When CONFIG_MODULES=n,\nthe btf_id of the \"struct module\" is missing:\n\nWARN: resolve_btfids: unresolved symbol module\n\nThus, the bpf_try_module_get() cannot do the correct refcounting.\n\nNot all subsystem's struct_ops requires the \"struct module *owner\" member.\ne.g. the recent sched_ext_ops.\n\nThis patch is to disable bpf_struct_ops registration if\nthe struct_ops has the \"struct module *\" member and the\n\"struct module\" btf_id is missing. The btf_type_is_fwd() helper\nis moved to the btf.h header file for this test.\n\nThis has happened since the beginning of bpf_struct_ops which has gone\nthrough many changes. The Fixes tag is set to a recent commit that this\npatch can apply cleanly. Considering CONFIG_MODULES=n is not\ncommon and the age of the issue, targeting for bpf-next also." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.8, "baseSeverity": "HIGH" }, "scenarios": [ { "lang": "en", "value": "AV:L - The attack is driven entirely through local syscalls — bpf(BPF_MAP_CREATE/MAP_UPDATE_ELEM/LINK_CREATE) to register the struct_ops congestion control, setsockopt(TCP_CONGESTION) to bind a socket to it, and close() to drop the map. Although the freed object is subsequently dereferenced while processing TCP ACKs, a remote peer cannot perform the registration/free setup.\nAC:L - On an affected kernel every step is deterministic and attacker-driven — register the struct_ops, attach it to a socket the attacker owns, close the fds to free the map, then drive traffic over loopback to hit the dangling icsk_ca_ops; there is no race and no dependence on memory layout the attacker cannot influence. The build-time CONFIG_MODULES=n precondition defines the vulnerable configuration rather than a condition to be won at exploit time, and it is trivially observable in advance (absent /proc/modules).\nPR:L - Creating the struct_ops map goes through bpf_token_capable(token, CAP_BPF), which BPF tokens explicitly delegate into unprivileged container user namespaces — the model container runtimes and BPF agents routinely use — and the socket, setsockopt(TCP_CONGESTION) and loopback-traffic halves of the attack need no capability at all.\nUI:N - The attacker performs the entire sequence with its own process, sockets and file descriptors; no victim action, mount, or configuration change by another user is required.\nS:U - The dangling tcp_congestion_ops pointer is dereferenced by the same kernel the attacker already has local access to; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed st_map allocation holding kvalue.data can be reclaimed and shaped by the attacker while sockets still read through icsk_ca_ops, turning the stale pointer into a controlled kernel-memory read primitive that leaks arbitrary kernel data.\nI:H - The kernel makes indirect calls through function pointers in the freed tcp_congestion_ops and into freed trampoline/bpf_prog_pack executable pages, giving a direct control-flow hijack primitive after heap or exec-page reclaim — full arbitrary write and code execution in kernel context.\nA:H - Even unweaponized, the use-after-free causes an oops or panic on the next congestion-control callback, and installing the bpf CA as the netns default poisons every new TCP socket in that namespace, wedging the network stack." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "include/linux/btf.h", "kernel/bpf/bpf_struct_ops.c", "kernel/bpf/btf.c" ], "versions": [ { "version": "1611603537a4b88cec7993f32b70c03113801a46", "lessThan": "b777b14c2a4a4e2322daf8e8ffd42d2b88831b17", "status": "affected", "versionType": "git" }, { "version": "1611603537a4b88cec7993f32b70c03113801a46", "lessThan": "2324fb4e92092837ee278fdd8d60c48ee1a619ce", "status": "affected", "versionType": "git" }, { "version": "1611603537a4b88cec7993f32b70c03113801a46", "lessThan": "96ea081ed52bf077cad6d00153b6fba68e510767", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "include/linux/btf.h", "kernel/bpf/bpf_struct_ops.c", "kernel/bpf/btf.c" ], "versions": [ { "version": "6.9", "status": "affected" }, { "version": "0", "lessThan": "6.9", "status": "unaffected", "versionType": "semver" }, { "version": "6.12.13", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.13.2", "lessThanOrEqual": "6.13.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.14", "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": "6.9", "versionEndExcluding": "6.12.13" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.9", "versionEndExcluding": "6.13.2" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.9", "versionEndExcluding": "6.14" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/b777b14c2a4a4e2322daf8e8ffd42d2b88831b17" }, { "url": "https://git.kernel.org/stable/c/2324fb4e92092837ee278fdd8d60c48ee1a619ce" }, { "url": "https://git.kernel.org/stable/c/96ea081ed52bf077cad6d00153b6fba68e510767" } ], "title": "bpf: Reject struct_ops registration that uses module ptr and the module btf_id is missing", "x_generator": { "engine": "bippy-1.2.0" } }, "adp": [ { "metrics": [ { "cvssV3_1": { "scope": "UNCHANGED", "version": "3.1", "baseScore": 7.8, "attackVector": "LOCAL", "baseSeverity": "HIGH", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "integrityImpact": "HIGH", "userInteraction": "NONE", "attackComplexity": "LOW", "availabilityImpact": "HIGH", "privilegesRequired": "LOW", "confidentialityImpact": "HIGH" } }, { "other": { "type": "ssvc", "content": { "id": "CVE-2024-58060", "role": "CISA Coordinator", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "version": "2.0.3", "timestamp": "2025-03-06T16:04:02.766596Z" } } } ], "problemTypes": [ { "descriptions": [ { "lang": "en", "type": "CWE", "cweId": "CWE-416", "description": "CWE-416 Use After Free" } ] } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-03-06T16:04:30.923Z" } } ] } }
