The OSD client tracks the progress of a\nsparse-read reply using a separate state machine, largely independent of\nthe messenger's state.\n\nIf a connection is lost mid-payload or the sparse-read state machine\nreturns an error, the sparse-read state is not reset. The OSD client\nwill then interpret the beginning of a new reply as the continuation of\nthe old one. If this makes the sparse-read machinery enter a failure\nstate, it may never recover, producing loops like:\n\n  libceph:  [0] got 0 extents\n  libceph: data len 142248331 != extent len 0\n  libceph: osd0 (1)...:6801 socket error on read\n  libceph: data len 142248331 != extent len 0\n  libceph: osd0 (1)...:6801 socket error on read\n\nTherefore, reset the sparse-read state in osd_fault(), ensuring retries\nstart from a clean state.","published":"2026-02-14T16:15:54.000Z","lastModified":"2026-10-19T19:17:39.000Z","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-667"],"affected":["linux/linux kernel"],"epss":{"score":0.00248,"percentile":0.15985,"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 (0.25%).
