Instead the whole thing\nneeds to be rebuilt if any change is requested. If the user does not\nspecify a translation then force the implicit values which will then fall\nthrough the logic into mlx5_ib_reg_user_mr() to allocate a completely new\nMR.\n\nSince implicit children were also touching the mr->pd, this removes\nanother case where the access was racy.","published":"2026-09-04T17:17:00.000Z","lastModified":"2026-09-04T17:17:00.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00161,"percentile":0.05258,"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":"unknown","text":"Not yet scored.
