{"schema":"threatline.record/2","record":{"id":"CVE-2026-98019","aliases":[],"summary":"bpf: mark a NULL call argument precise","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: mark a NULL call argument precise\n\ncheck_func_arg() allows bpf_register_is_null() for nullable arguments\nw/o marking the underlying scalar register precise. Hence a checkpoint\ncreated on such a path would prune against arbitrary scalar value.\n\ncheck_helper_call() enforces second parameter of the\nbpf_get_local_storage() to be zero, w/o marking the underlying scalar\nregister precise. Hence a checkpoint created on such a path would\nprune against arbitrary scalar value.\n\nGrouping these two into one patch, as they share the same fixes tag.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98019","source_modified_at":"2026-10-21T12:54:04.100Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"b5dc0163d8fd78e64a7e21f309cf932fda34353e","lessThan":"febbb66e682d8328f7c5bcbdd5e4291abab2e858","status":"affected","versionType":"git"},{"version":"b5dc0163d8fd78e64a7e21f309cf932fda34353e","lessThan":"627089c278df58749f25686c6a3caf7e181b5951","status":"affected","versionType":"git"},{"version":"b5dc0163d8fd78e64a7e21f309cf932fda34353e","lessThan":"b1fe6379e401b8ce0f561cb4d84af2b70b4343c3","status":"affected","versionType":"git"},{"version":"b5dc0163d8fd78e64a7e21f309cf932fda34353e","lessThan":"69a9ad004ccf5d45e534c7d503f47f643abe64b7","status":"affected","versionType":"git"},{"version":"b5dc0163d8fd78e64a7e21f309cf932fda34353e","lessThan":"1a3a10b030c96ea88868ccc060a16827c01eaa5a","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98019","source_modified_at":"2026-10-21T12:54:04.100Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.3","status":"affected"},{"version":"0","lessThan":"5.3","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.114","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.57","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-2026-98019","source_modified_at":"2026-10-21T12:54:04.100Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"627089c278df58749f25686c6a3caf7e181b5951","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98019","source_modified_at":"2026-10-21T12:54:04.100Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"69a9ad004ccf5d45e534c7d503f47f643abe64b7","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98019","source_modified_at":"2026-10-21T12:54:04.100Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"1a3a10b030c96ea88868ccc060a16827c01eaa5a","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05754,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:23:40.303Z","modified_at":"2026-10-21T12:54:04.100Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98019","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:54:04.100Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98019","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/febbb66e682d8328f7c5bcbdd5e4291abab2e858"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/627089c278df58749f25686c6a3caf7e181b5951"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/b1fe6379e401b8ce0f561cb4d84af2b70b4343c3"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/69a9ad004ccf5d45e534c7d503f47f643abe64b7"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/1a3a10b030c96ea88868ccc060a16827c01eaa5a"}],"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":"2026-10-21T12:54:04.100Z","content_hash":"ab322e0c2c1df126ee730fbb9a9413f381ae50637b3674940d2c16784ed19d6d"}}
