The function however\nlooped purex->entry_count times starting at ring_ptr. As entry_count\nincludes the head, this consumed one entry too many: it stamped\nRESPONSE_PROCESSED on the next, unrelated IOCB and advanced the ring\npast it, silently dropping a legitimate firmware response. The head\nIOCB's signature was also never marked.\n\nMark the head processed and account for it, then consume only the\nentry_count - 1 continuation IOCBs, matching __qla_copy_purex_to_buffer().","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/31715d1e1cbf3a37ce3452635c5602f73fd7abd4","https://git.kernel.org/stable/c/3ba019bdd89d931499d9476456b5d9c7ab7fa753","https://git.kernel.org/stable/c/6e3f129538c32d0019437197735912308c161843","https://git.kernel.org/stable/c/a136c311676fd1010b1bde3bcfd410caa2fa040f","https://git.kernel.org/stable/c/bd1534d4afab47f13dfc27fff6f59dd859a0ac3a"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-93242","score":0.00231,"percentile":0.13805,"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).
