When processing base64-encoded image data via the /api/chat endpoint, the application fails to validate that the decoded data represents valid media before passing it to the mtmd_helper_bitmap_init_from_buf function. This function can return NULL for malformed input, but the code does not check this return value before dereferencing the pointer in subsequent operations. A remote attacker can exploit this by sending specially crafted base64 image data that decodes to invalid media, causing a segmentation fault and crashing the runner process. This results in a denial of service condition where the model becomes unavailable to all users until the service is restarted.","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-2025-15514","url":"https://www.suse.com/security/cve/CVE-2025-15514"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1256527 for CVE-2025-15514","url":"https://bugzilla.suse.com/1256527"}],"title":"SUSE CVE CVE-2025-15514","tracking":{"current_release_date":"2026-01-14T00:28:37Z","generator":{"date":"2026-01-14T00:28:37Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2025-15514","initial_release_date":"2026-01-14T00:28:37Z","revision_history":[{"date":"2026-01-14T00:28:37Z","number":"2","summary":"references added,severity changed from  to moderate"}],"status":"interim","version":"2"}}}
