Updating rd_offset prematurely can lead to the host accessing\nan uninitialized or incomplete element, resulting in data corruption.\n\nInvoke the buffer write before updating rd_offset to ensure the element\nis fully written before signaling its availability.","published":"2025-07-25T15:15:28.000Z","lastModified":"2026-07-30T06:23:14.000Z","status":"Modified","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-908"],"affected":["linux/linux kernel"],"epss":{"score":0.00465,"percentile":0.401,"date":"2026-10-27","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 (0.46%).
