The w_rx_aar_register() function copies the attacker-controlled host field from the SIP `Via` header into a fixed 46-byte stack buffer without validating its length. An unauthenticated remote attacker can trigger the vulnerability with a crafted SIP `REGISTER` request, causing stack corruption and termination of the affected Kamailio instance, resulting in denial of service.","epss":null,"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/kamailio/kamailio/issues/4953"}],"kev":null,"metrics":[{"score":7.5,"severity":"high","source":"ADP: CISA-ADP","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"}],"modifiedAt":1793645718235,"publishedAt":1793577600000,"references":[{"source":"CNA: mitre","tags":[],"url":"https://github.com/kamailio/kamailio/issues/4953"},{"source":"CNA: mitre","tags":[],"url":"https://gist.github.com/hackeryounow/f5af75502ea6df600428c46bb9bbf39e"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/kamailio/kamailio/issues/4953"},{"source":"cve@mitre.org","tags":[],"url":"https://gist.github.com/hackeryounow/f5af75502ea6df600428c46bb9bbf39e"},{"source":"cve@mitre.org","tags":[],"url":"https://github.com/kamailio/kamailio/issues/4953"}],"remediation":[],"revision":"5358785bb42f6ccf50a3b21402baf61b898bb072cfe4d36f5dca68a897fa7008","sources":[{"modifiedAt":1793645718235,"name":"CNA: mitre","retrievedAt":1793646519557,"url":"https://www.cve.org/CVERecord?id=CVE-2026-106804"},{"modifiedAt":1793639853453,"name":"NVD","retrievedAt":1793643573008,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-106804"}],"ssvc":{"assessedAt":1793645675760,"automatable":"yes","exploitation":"poc","source":"ADP: CISA-ADP","technicalImpact":"partial"},"status":"published","title":"CVE-2026-106804","updatedAt":1793646519557}
