{"schema":"threatline.record/2","record":{"id":"CVE-2026-98045","aliases":[],"summary":"bpf: Mark faultable stack helpers as sleepable","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbpf: Mark faultable stack helpers as sleepable\n\nThe faultable variants of bpf_get_stack() and bpf_get_task_stack() pass\nmay_fault=true into the common stack collection code. Resolving user-space\nbuild IDs may then call build_id_parse_file() and block on filesystem\nreads.\n\nNeither helper prototype sets might_sleep. Since prototype selection uses\nthe sleepability of the whole program, the verifier can still allow these\nhelpers from a non-sleepable region within that program, such as an\nexplicit RCU or preemption-disabled region. The task-stack helper can also\nbe called from a non-sleepable timer callback of a sleepable program.\n\nMark both faultable prototypes as sleepable. The existing helper context\ncheck then rejects these calls while continuing to allow them in genuinely\nsleepable contexts.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98045","source_modified_at":"2026-10-19T09:12:51.065Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"d4dd9775ec242425576af93daadb80a34083a53c","lessThan":"44b8d370f2725bad215da3e67668e98ba96671bd","status":"affected","versionType":"git"},{"version":"d4dd9775ec242425576af93daadb80a34083a53c","lessThan":"3014e8a8bdad55075d89836ad9c10710a9a69837","status":"affected","versionType":"git"},{"version":"d4dd9775ec242425576af93daadb80a34083a53c","lessThan":"19e8d5a98afd071d8c1c5adeccf92b3c42eddc70","status":"affected","versionType":"git"},{"version":"d4dd9775ec242425576af93daadb80a34083a53c","lessThan":"9d02927fdf4e930893c92e35fed01a2704496900","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98045","source_modified_at":"2026-10-19T09:12:51.065Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.12","status":"affected"},{"version":"0","lessThan":"6.12","status":"unaffected","versionType":"semver"},{"version":"6.12.111","lessThanOrEqual":"6.12.*","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-2026-98045","source_modified_at":"2026-10-19T09:12:51.065Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"44b8d370f2725bad215da3e67668e98ba96671bd","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98045","source_modified_at":"2026-10-19T09:12:51.065Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"3014e8a8bdad55075d89836ad9c10710a9a69837","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98045","source_modified_at":"2026-10-19T09:12:51.065Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"19e8d5a98afd071d8c1c5adeccf92b3c42eddc70","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98045","source_modified_at":"2026-10-19T09:12:51.065Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"9d02927fdf4e930893c92e35fed01a2704496900","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05758,"score_date":"2026-10-23"},"published_at":"2026-09-25T10:23:56.089Z","modified_at":"2026-10-19T09:12:51.065Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98045","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:12:51.065Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98045","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/44b8d370f2725bad215da3e67668e98ba96671bd"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/3014e8a8bdad55075d89836ad9c10710a9a69837"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/19e8d5a98afd071d8c1c5adeccf92b3c42eddc70"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/9d02927fdf4e930893c92e35fed01a2704496900"}],"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":"2026-10-19T09:12:51.065Z","content_hash":"b38bac2a2bea940f73cff599b1ec36ff30cd838515af4a1aeac3d565f64141c7"}}
