This patch changes the interface to dm-io, so that\nit reports two error bitmaps - error_bits and unsup_bits. The unsup_bit\nbitmap tracks BLK_STS_NOTSUPP or BLK_STS_INVAL errors, the error_bits\nbitmap tracks all the other errors.\n\ndm-raid1 is changed so that it won't fail a leg if it receives an error\nin the unsup_bits bitmap.\n\nThis patch (with 62dc37a819a5) fixes misbehavior if the user uses\nunaligned bio vectors on dm-raid1.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/15fc1ec72e1f8089063d298550ada727e18f114a","https://git.kernel.org/stable/c/47a5e62f39875f371bded6e34ffb9cf15ccd813d","https://git.kernel.org/stable/c/49694a363f7ecd5a52d1ea1a13c287ad6d196c35"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-89577","score":0.00203,"percentile":0.10181,"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).
