The command-set filter dereferences req->ns,\nbut this handler never calls nvmet_req_find_ns(), so req->ns is always\nNULL (nvmet_req_init() resets it to NULL). As soon as an enabled\nnamespace with an NSID greater than the requested value exists,\nreq->ns->csi dereferences a NULL pointer and oopses.\n\nBesides the crash, the comparison is logically wrong: to filter the list\nby command set it must test the command set of the namespace being\niterated, not a single fixed value. Use the loop variable ns->csi.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/123d664ac98d6f3464462ad4a530474b91ba9890","https://git.kernel.org/stable/c/2bc1e33ff6a558c8ceef7c0077f3ef70a15fcba2","https://git.kernel.org/stable/c/61dc1a37e04d4003a19095f54883358330034a39","https://git.kernel.org/stable/c/79aba4c9403419d822972d2851f2a96a2c0531cf"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80813","score":0.00209,"percentile":0.10938,"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).
