The helper can keep\nleftover bytes between callbacks and may receive multiple packets in one\ncallback, so a single count value is not constrained by one packet\nlength.\n\nCheck that the incoming chunk fits in the remaining receive buffer space\nbefore memcpy(). If it does not, drop the staged data and consume the\nbytes instead of overflowing rx_buffer.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.0},"cwes":["CWE-120"],"references":["https://git.kernel.org/stable/c/0339a746ff7cd3f9d10f565e89c99dc93191e58d","https://git.kernel.org/stable/c/1214bf28965ceaf584fb20d357731264dd2e10e1","https://git.kernel.org/stable/c/663c2728a6d0f781044431111b53a27f71027e48","https://git.kernel.org/stable/c/fb91d4e49fcbea0b5091394ac5b8f7d4124265c3"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-46332","score":0.00193,"percentile":0.09001,"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).
