If the creation of p9_trans_fd fails,\np9_fd_create_tcp() and p9_fd_create_unix() will return an\nerror directly instead of releasing the cscoket, which will\nresult in a socket leak.\n\nThis patch adds sock_release() to fix the leak issue.","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-401"],"references":["https://git.kernel.org/stable/c/0396227f4daf4792a6a8aaa3b7771dc25c4cd443","https://git.kernel.org/stable/c/2d24d91b9f44620824fc37b766f7cae00ca32748","https://git.kernel.org/stable/c/8782b32ef867de7981bbe9e86ecb90e92e8780bd","https://git.kernel.org/stable/c/8b14bd0b500aec1458b51cb621c8e5fab3304260","https://git.kernel.org/stable/c/aa08323fe18cb7cf95317ffa2d54ca1de8e74ebd"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:56:33.105311382+00:00"},"epss":{"cve":"CVE-2022-49020","score":0.00236,"percentile":0.1461,"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).
