{"schema":"threatline.record/2","record":{"id":"CVE-2026-99143","aliases":[],"summary":"tracing: Keep the predicate limit separate from program capacity","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ntracing: Keep the predicate limit separate from program capacity\n\npredicate_parse() adds two to nr_preds to reserve the terminal TRUE\nand FALSE entries. It also uses that increased value as the limit for\nparsed predicates. If the initial count is smaller than the number\nactually parsed, the program can fill the allocation and subsequent\naccesses can go past its end.\n\nKeep nr_preds as the predicate limit and use a separate value for the\nallocation size. This leaves space for both terminal entries and a\nzeroed entry when parsing stops at the limit.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99143","source_modified_at":"2026-10-28T10:34:54.527Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"39f7c41c908bc82947ce47cdd021520ff486c53f","lessThan":"2058a1fe791bb30fd6e4875a7ada3237076c8541","status":"affected","versionType":"git"},{"version":"39f7c41c908bc82947ce47cdd021520ff486c53f","lessThan":"68ecc9510bb82dd78585c02bd5357f34ee16b153","status":"affected","versionType":"git"},{"version":"39f7c41c908bc82947ce47cdd021520ff486c53f","lessThan":"803aa6fc2dbea25ab9d3ed19eca1c96d0ab17445","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99143","source_modified_at":"2026-10-28T10:34:54.527Z","fetched_at":"2026-10-28T15:55:58.673066Z","product":"Linux","vendor":"Linux","versions":[{"version":"6.6","status":"affected"},{"version":"0","lessThan":"6.6","status":"unaffected","versionType":"semver"},{"version":"6.18.59","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.13","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-2026-99143","source_modified_at":"2026-10-28T10:34:54.527Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"2058a1fe791bb30fd6e4875a7ada3237076c8541","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99143","source_modified_at":"2026-10-28T10:34:54.527Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"68ecc9510bb82dd78585c02bd5357f34ee16b153","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-99143","source_modified_at":"2026-10-28T10:34:54.527Z","fetched_at":"2026-10-28T15:55:58.673066Z","package":{"name":"Linux","ecosystem":null},"version":"803aa6fc2dbea25ab9d3ed19eca1c96d0ab17445","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T10:34:54.527Z","modified_at":"2026-10-28T10:34:54.527Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-99143","fetched_at":"2026-10-28T15:55:58.673066Z","source_modified_at":"2026-10-28T10:34:54.527Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/2058a1fe791bb30fd6e4875a7ada3237076c8541"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/68ecc9510bb82dd78585c02bd5357f34ee16b153"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/803aa6fc2dbea25ab9d3ed19eca1c96d0ab17445"}],"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":"2026-10-28T10:34:54.527Z","content_hash":"a3c17763368d1fe4b0b1126611e3a29637bcae077acc668bec23c9c4bebc956d"}}
