However, the allocated\nresource was not given a name, which causes the kernel resource tree\nto contain an entry marked as \"<BAD>\" under /proc/iomem on x86\nplatforms.\n\nDuring boot, this unnamed resource can lead to a critical hang because\nsubsequent resource lookups and conflict checks fail to handle the\ninvalid entry properly.","published":"2026-01-14T15:16:01.000Z","lastModified":"2026-10-19T19:17:13.000Z","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-401","CWE-20"],"affected":["linux/linux kernel"],"epss":{"score":0.00178,"percentile":0.07313,"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 (0.18%).
