For\nversion 1 headers the packet set starts later in the header, so this can\noverstate the available buffer.\n\nPass the actual packet set buffer length from the caller and calculate\nper-packet limits from the remaining bytes in that buffer.  Recompute the\nremaining length after consuming a tag 3 packet before parsing the\nfollowing tag 11 packet.","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:N/A:H","score":7.1},"cwes":[],"references":["https://git.kernel.org/stable/c/2602b79c5b3e2f6fce12e38a670f8e3fda4e46a2","https://git.kernel.org/stable/c/329de8b9e988b152b938f09224670d97bada0b96","https://git.kernel.org/stable/c/3bd9bb3e167a7c14a50423f6ff03ee0fb007199d","https://git.kernel.org/stable/c/66a87559ecb26afe80ad512faf728a158e2b81da","https://git.kernel.org/stable/c/747fd45be396a6aea3420ab657a0ab4e60185b05"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89608","score":0.00164,"percentile":0.05569,"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).
