However, it still\nwould try to take the pool_lock in an attempt to save a stack trace in the\ncurrent pool (if space is available).\n\nThis could result in deadlock if an NMI is handled while pool_lock is\nalready held.  To avoid deadlock, only try to take the lock in NMI context\nand give up if unsuccessful.\n\nThe documentation is fixed to clearly convey this.","published":"2025-01-11T13:15:23.000Z","lastModified":"2026-06-17T07:58:57.000Z","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-667"],"affected":["linux/linux kernel"],"epss":{"score":0.00143,"percentile":0.03605,"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 (0.14%).
