However, if we later reduced the plaintext data length\nvia socket policy, we failed to recalculate the ciphertext length.\n\nThis results in transmitting buffers containing uninitialized data during\nciphertext transmission.\n\nThis causes uninitialized bytes to be appended after a complete\n\"Application Data\" packet, leading to errors on the receiving end when\nparsing TLS record.","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":["CWE-908"],"references":["https://git.kernel.org/stable/c/0e853c1464bcf61207f8b5c32d2ac5ee495e859d","https://git.kernel.org/stable/c/16aca8bb4ad0d8a13c8b6da4007f4e52d53035bb","https://git.kernel.org/stable/c/178f6a5c8cb3b6be1602de0964cd440243f493c9","https://git.kernel.org/stable/c/1e480387d4b42776f8957fb148af9d75ce93b96d","https://git.kernel.org/stable/c/6ba20ff3cdb96a908b9dc93cf247d0b087672e7c"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:07:46.309729541+00:00"},"epss":{"cve":"CVE-2025-38608","score":0.00415,"percentile":0.35481,"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).
