That is, the check itself is valid and snd_BUG_ON()\nshould be dropped from there.  Otherwise it's confusing as if it were\na real bug, as recently syzbot stumbled on it.","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/00f5f1bbf815a39e9eecb468d12ca55d3360eb10","https://git.kernel.org/stable/c/02b94885b2fdf1808b1874e009bfb90753f8f4db","https://git.kernel.org/stable/c/a80369c8ca50bc885d14386087a834659ec54a54","https://git.kernel.org/stable/c/ad72c3c3f6eb81d2cb189ec71e888316adada5df","https://git.kernel.org/stable/c/c43991065f36f7628cd124e037b8750c4617a7a7"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2022-49772","score":0.00202,"percentile":0.10226,"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).
