So the new request was not being\nfactored in the spam calculation. Fix this by moving the logic after\nthe new range has been inserted.\n\nAlso, the detection logic for ArrayRange was missing altogether which\nmeant large spamming transactions could get away without being detected.\nFix this by implementing an equivalent low_oneway_space() in ArrayRange.\n\nNote that I looked into centralizing this logic in RangeAllocator but\niterating through 'state' and 'size' got a bit too complicated (for me)\nand I abandoned this effort.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":[],"references":["https://git.kernel.org/stable/c/4fc87c240b8f30e22b7ebaae29d57105589e1c0b","https://git.kernel.org/stable/c/8d34c993a9a156e657e43cb95186980745cc3597","https://git.kernel.org/stable/c/edf685946c4acbe57cb96f8d5f3c07e9a2e973c8"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-43435","score":0.00121,"percentile":0.01875,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
