If wait_read_barrier() fails for a REQ_NOWAIT\nread, the bio is completed and the function returns immediately. In this\ncase the existing r1_bio is leaked.\n\nThis fixes a leak of pre-allocated r1_bio structures for retried reads.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/69ad6ce47f9bf2b9fe0ed69b042db993d33bbf12","https://git.kernel.org/stable/c/6d92dbd73d19a0622f60352ce9d9379f7a760112","https://git.kernel.org/stable/c/c66ed3e6371f5dba8f5d8ab810d6683ddc99201e","https://git.kernel.org/stable/c/c6e6354295845698d2fdfa20b71fc404786f7e93","https://git.kernel.org/stable/c/d1eda529a4bf6b866d02755723ee0eb1f037a5ed"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72437","score":0.00215,"percentile":0.11927,"date":"2026-10-31"},"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).
