When processing a specially crafted AX.25 frame containing a MIC-E message with an empty or truncated comment field, the application triggers an unhandled assertion checking for a non-empty comment. This assertion failure causes immediate process termination, allowing a remote, unauthenticated attacker to cause a denial of service by sending malformed APRS traffic.","state":0,"publishedAt":"2025-12-22T21:29:46.85+00:00","modifiedAt":"2026-10-29T20:19:02.849+00:00","affected":[{"ecosystem":"Vendor product","name":"direwolf","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageName\": \"direwolf\",\n                    \"packageURL\": \"pkg:github/wb2osz/direwolf\",\n                    \"product\": \"Dire Wolf\",\n                    \"repo\": \"https://github.com/wb2osz/direwolf\",\n                    \"vendor\": \"wb2osz\",\n                    \"versions\": [\n                        {\n                            \"lessThanOrEqual\": \"1.8.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"3658a878920803bbb69a4567579dcc4d6cb80a92\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/marlinkcyber/advisories/blob/main/advisories/MCSAID-2025-010-direwolf-stack-buffer-overflow-kiss-frame.md","https://github.com/wb2osz/direwolf/issues/618","https://github.com/wb2osz/direwolf/commit/3658a87","https://www.vulncheck.com/advisories/wb2osz-direwolf-reachable-assertion-dos"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-34458","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-34458","identifiers":["CVE-2025-34458"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
