The normal txqcqs array only\ncontains the regular queue pairs, so using that index to set rxq->partner\ncan read one entry past txqcqs[] and then write through the derived\npointer.\nOnly link RX/TX partners for normal queue-pair indexes. Leave the hwstamp\nRX queue unpaired, and make the XDP_TX path abort cleanly if an RX queue\nhas no TX partner.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/39fc615e355b65b8d43be30da57aa95ae6eaf688","https://git.kernel.org/stable/c/881a805a8029ba48c0ce81c6674910f8d83f7afb","https://git.kernel.org/stable/c/d92255b405fb6f5acca408239ccd742e0a42c9cb","https://git.kernel.org/stable/c/ea081b4435515ac7177eb598a3c0678d1b9e7911","https://git.kernel.org/stable/c/f3868046e8e2e761d4d943a232bd109ff22a7d5b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80779","score":0.00168,"percentile":0.06027,"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).
