The map slot is cleared by\nqla25xx_free_req_que() (ha->req_q_map[que_id] = NULL under mq_lock)\nduring queue teardown, while the response-queue interrupt that drives\nqla2x00_error_entry() is still registered (the IRQ is released later in\nqla25xx_free_rsp_que()). If the slot is set to NULL between the two\nreads, req becomes NULL and is dereferenced.\n\nRead the slot once into req and NULL-check the local before use. mq_lock\nis a mutex and cannot be taken from interrupt context, so the single\nread plus local check is the appropriate fix for the reported NULL\ndereference.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/1b995cf4157465357d66ba096e7cdaafab9972e7","https://git.kernel.org/stable/c/1c90b74e484ba48f31944fe04963d99e01ac3767","https://git.kernel.org/stable/c/35124cfa9898b2088ee72859e573e0876aff66fc","https://git.kernel.org/stable/c/5dd9bec8004ba93cee8b689bf54ce294f59e5e3c","https://git.kernel.org/stable/c/c845f2597787ef70159a32566669e308b2807a56"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-89845","score":0.00216,"percentile":0.11984,"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).
