A\nsplice therefore keeps delivering records on a connection that\nrecvmsg() and read_sock() refuse to read.\n\nRead async_wait.err in tls_sw_splice_read() as the other two readers\ndo.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/06c2a53604fa1dc4820063828d7dadb3675b7af8","https://git.kernel.org/stable/c/18ae1e95f20867106a28820c208a9cec99dda861","https://git.kernel.org/stable/c/4b177911eb9f799e9841c2f87c75b08cb112757a","https://git.kernel.org/stable/c/82d9269f01ebfd835b6256aa17016a974cbbc647","https://git.kernel.org/stable/c/976df67f463db1fddaf2a32fb04f57ad2891a23d"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80904","score":0.00161,"percentile":0.0525,"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).
