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.","published":"2024-10-21T20:15:13.000Z","lastModified":"2026-06-17T05:16:52.000Z","status":"Analyzed","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-401"],"affected":["linux/linux kernel"],"epss":{"score":0.00236,"percentile":0.14426,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.24%).
