A device response shorter than that expectation can therefore\nbe read beyond the skb payload.\n\nRecord -EMSGSIZE for a short response, complete the waiter, and return\nthe stored status from the command path. This also prevents callers from\nconsuming stale response bytes as a successful reply.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/03ef61d05aa26022327f971b790f07e6bf6e35d6","https://git.kernel.org/stable/c/93ce8ea70451e800601bc9444aa33043de15d67b","https://git.kernel.org/stable/c/a3b0137c855a61371d9cf9993b8bcc33c9798202","https://git.kernel.org/stable/c/e0c21130c1c7791ba73b19a3a9ea767c8cd43745"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-98828","score":0.002,"percentile":0.09713,"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).
