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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-667"],"references":["https://git.kernel.org/stable/c/10b7c72810364226f7b27916ea3e2a4f870bc04b","https://git.kernel.org/stable/c/11194b416ef95012c2cfe5f546d71af07b639e93","https://git.kernel.org/stable/c/90a60fe61908afa0eaf7f8fcf1421b9b50e5f7ff","https://git.kernel.org/stable/c/e94075e950a6598e710b9f7dffea5aa388f40313"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-23136","score":0.00248,"percentile":0.15972,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
