A corrupted attribute can drive that addition past\nthe representable range.\n\nOne corrupt runlist shape sets the accumulated LCN to S64_MAX and\nthen adds a delta of 1 in the next mapping-pairs entry.\n\nSigned overflow is undefined and can turn an invalid runlist into a\ndifferent set of physical clusters.\n\nCheck the LCN addition for overflow before storing the next run.","published":"2026-08-15T06:21:39.000Z","lastModified":"2026-10-21T13:19:34.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":[],"epss":{"score":0.00671,"percentile":0.51832,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.67%).
