However, it's still vulnerable to infinite\nloops that come in via the next_unlinked pointers.\n\nFix this problem by remembering which inodes we've already seen and\nchecking new agino pointers against that.  If a bit is already set,\neither this is a loop or the inode has nonzero link count.  We'll deal\nwith the second case in a subsequent patch.","published":"2026-08-26T15:17:07.000Z","lastModified":"2026-08-26T15:17:07.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00168,"percentile":0.06044,"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.
