The\n%s conversion skips leading whitespace, while strcspn() does not.\n\nIf a client debug entry starts with a space, the allocation can be sized\nfor an empty keyword while sscanf() copies the following non-empty token.\nThis can write past the end of the allocated keyword buffer.\n\nSkip leading spaces before computing the keyword length so the allocation\nmatches the string parsed by sscanf().","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/0ef38d53bca5ea1375fea0d3d11e9727df064b85","https://git.kernel.org/stable/c/116d14f29a0524853c9316f32a2ac06cff5d4bf6","https://git.kernel.org/stable/c/15d79c806231e62a7b746d3b42626810004e1b27","https://git.kernel.org/stable/c/173bfd69696815bcf1c052f61cb69c26cca4e443","https://git.kernel.org/stable/c/1774c5b3713add32fe15ab0d3db4b73355f94e35"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89497","score":0.00129,"percentile":0.0254,"date":"2026-10-25"},"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).
