This can\npotentially lead to a use-after-free in case a larb device has not yet\nbeen bound to its driver so that the iommu driver probe defers.\n\nFix this by keeping the references as expected while the iommu driver is\nbound.","published":"2026-01-13T16:16:07.000Z","lastModified":"2026-06-17T10:03:36.000Z","status":"Analyzed","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-416"],"affected":["linux/linux kernel"],"epss":{"score":0.0015,"percentile":0.04103,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.15%).
