{"schema":"threatline.record/2","record":{"id":"CVE-2026-98060","aliases":[],"summary":"bpf: Reject resilient lock operations in rbtree callbacks","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Reject resilient lock operations in rbtree callbacks\n\n__bpf_rbtree_add() keeps parent and link pointers live across calls to the\nprogram-supplied comparison callback. The verifier therefore requires the\nroot's lock to remain held throughout the callback.\n\nThe helper path enforces this rule for bpf_spin_lock() and\nbpf_spin_unlock(), but the resilient lock kfunc argument path does not.\nSince resilient locks may protect BPF rbtree roots, a callback can release\nthe root lock and let another CPU remove and free the node referenced by\nthe in-progress tree walk. The walk then resumes using freed pointers.\n\nReject resilient lock kfuncs in an rbtree comparison callback, matching\nthe existing policy for the spin lock helpers. Resilient-lock-protected\ntrees remain valid when their comparison callbacks leave lock state alone.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98060","source_modified_at":"2026-10-19T09:13:08.516Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"0de2046137f976e7302d43ac01d9894d07ac1fff","lessThan":"cc2e065ed206aecd9b94564779244f3ffb26e356","status":"affected","versionType":"git"},{"version":"0de2046137f976e7302d43ac01d9894d07ac1fff","lessThan":"71930202a0a0c49f0a3b45b41907a074cb780266","status":"affected","versionType":"git"},{"version":"0de2046137f976e7302d43ac01d9894d07ac1fff","lessThan":"7b7b8b5960102566bd625ae829d1f330c5b5d104","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98060","source_modified_at":"2026-10-19T09:13:08.516Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98060","source_modified_at":"2026-10-19T09:13:08.516Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"71930202a0a0c49f0a3b45b41907a074cb780266","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98060","source_modified_at":"2026-10-19T09:13:08.516Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"7b7b8b5960102566bd625ae829d1f330c5b5d104","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00166,"percentile":0.05524,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:24:05.380Z","modified_at":"2026-10-19T09:13:08.516Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98060","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:13:08.516Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98060","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/cc2e065ed206aecd9b94564779244f3ffb26e356"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/71930202a0a0c49f0a3b45b41907a074cb780266"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/7b7b8b5960102566bd625ae829d1f330c5b5d104"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-19T09:13:08.516Z","content_hash":"0e61030563e4653ba1fd82c9f9457006121ffefd080c729d97a16bffc643f73c"}}
