The function mbedtls_x509_string_to_names() takes a head argument that is documented as an output argument. The documentation does not suggest that the function will free that pointer; however, the function does call mbedtls_asn1_free_named_data_list() on that argument, which performs a deep free(). As a result, application code that uses this function (relying only on documented behavior) is likely to still hold pointers to the memory blocks that were freed, resulting in a high risk of use-after-free or double-free. In particular, the two sample programs x509/cert_write and x509/cert_req are affected (use-after-free if the san string contains more than one DN).","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-2025-47917","url":"https://www.suse.com/security/cve/CVE-2025-47917"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1246783 for CVE-2025-47917","url":"https://bugzilla.suse.com/1246783"}],"title":"SUSE CVE CVE-2025-47917","tracking":{"current_release_date":"2025-08-07T23:22:43Z","generator":{"date":"2025-07-21T23:22:27Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2025-47917","initial_release_date":"2025-07-21T23:22:27Z","revision_history":[{"date":"2025-07-21T23:22:27Z","number":"2","summary":"Current version"},{"date":"2025-08-07T23:22:43Z","number":"3","summary":"Current version"}],"status":"interim","version":"3"}}}
