When processing crafted KISS frames that reach the maximum allowed frame length (MAX_KISS_LEN), the function appends a terminating FEND byte without reserving sufficient space in the stack buffer. This results in an out-of-bounds write followed by an out-of-bounds read during the subsequent call to kiss_unwrap(), leading to stack memory corruption or application crashes. This vulnerability may allow remote unauthenticated attackers to trigger a denial-of-service condition.","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-2025-34457","url":"https://www.suse.com/security/cve/CVE-2025-34457"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1255474 for CVE-2025-34457","url":"https://bugzilla.suse.com/1255474"}],"title":"SUSE CVE CVE-2025-34457","tracking":{"current_release_date":"2025-12-24T00:29:40Z","generator":{"date":"2025-12-24T00:29:40Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2025-34457","initial_release_date":"2025-12-24T00:29:40Z","revision_history":[{"date":"2025-12-24T00:29:40Z","number":"2","summary":"references added,severity changed from  to moderate"}],"status":"interim","version":"2"}}}
