After taking the folio lock, the current code treats that state\nas a read error and returns -EIO.\n\nThat can make a previous transient read failure sticky.  If the failed read\nleft a not-uptodate folio in the mapping, later callers find that folio and\nfail instead of retrying the read.\n\nKeep the existing page-cache insertion and locking order, but retry the\nMerkle item read when a not-uptodate folio is found in the mapping.  Also\nunlock the folio when read_key_bytes() fails so that a later caller can\nlock it and retry the read.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/12b6d1a1715cbced2e445ca353f9c9987b8636e2","https://git.kernel.org/stable/c/81241f734f0f662378f5ffc53882b012923e6fe5","https://git.kernel.org/stable/c/8cc569696dac51fc62bb39b3b8f530582b916d29","https://git.kernel.org/stable/c/90e9eae1b5907fa36620ffb7f4f1a4afa9333427","https://git.kernel.org/stable/c/c1fa005cdf3b7ff14cdfd7d512830088a3fc256b"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-90262","score":0.002,"percentile":0.09768,"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).
