Enabling swiotlb is one such case that\ncan change the result. The nvme driver needs to save the mapped dma\nvectors to be unmapped later, so allocate as needed during iteration\nrather than assume it was always allocated at the beginning. This fixes\na NULL dereference from accessing an uninitialized dma_vecs when the\ndevice dma unmapping requirements change mid-iteration.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2026-23174","url":"https://www.suse.com/security/cve/CVE-2026-23174"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"}],"title":"SUSE CVE CVE-2026-23174","tracking":{"current_release_date":"2026-02-16T00:25:39Z","generator":{"date":"2026-02-16T00:25:39Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2026-23174","initial_release_date":"2026-02-16T00:25:39Z","revision_history":[{"date":"2026-02-16T00:25:39Z","number":"2","summary":"references added,severity changed from  to not set"}],"status":"interim","version":"2"}}}
