Both the tracepoint\nand the driver callback consume the complete parameters block, not merely\nreq_type. Do not pass a short individual agreement to the driver.\nBroadcast agreements remain unchanged because they are rejected locally\nafter accessing only req_type.\n\n[edit commit message to not overclaim lack of validation nor\n understate driver impact]","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":[],"references":["https://git.kernel.org/stable/c/0502d5077e419427d80f4d46ba95d0067f5fb916","https://git.kernel.org/stable/c/09d60d1f72e6598241490eb6c4e97245af895c09","https://git.kernel.org/stable/c/47fb04c3826e1f90271d405523043d6708b9072a","https://git.kernel.org/stable/c/92fcd0f30dc8e51f252589b082d46851d295cc1a","https://git.kernel.org/stable/c/ade9e2f0f7f4d3089600ac2af8ef0b91746f923b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-80722","score":0.00239,"percentile":0.14795,"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).
