Otherwise a sysfs read can\ntrigger an oops.\nCommit 17f09d3f619a (\"SUNRPC: Check if the xprt is connected before\nhandling sysfs reads\") appears to attempt to fix this problem, but it\nonly narrows the race window.","published":"2024-07-16T12:15:06.000Z","lastModified":"2026-10-03T11:17:25.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":4.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-476"],"affected":["linux/linux kernel"],"epss":{"score":0.00285,"percentile":0.20818,"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 (0.29%).
